What is the measure of ∠ACB ? Enter your answer in the box ...
From the figure we know that angle A is 90 degrees. Angle B is 55 degrees. We need to find the angle C which is ∠ACB. By angle sum property the sum of three angles is 180 degrees. 55+90+∠ACB=180. 145+∠ACB=180. Subtract 145 from both sides. ∠ACB=180 - 145 =35 degrees. Hence, the measure of triangle ∠ACB is 35 degrees in the triangle.
If angle OBA is 48degrees .Determine the angle ACB
Since angle OBA is 48 degrees, the measure of arc AD is 96 degrees. Since BD is a diameter, arc DAB is 180 degrees, so minor arc AB is 84 degrees. So side AB of the inscribed triangle divides the circle into a minor arc AB of measure 84 degrees and a major arc ADB of measure 276 degrees. There are then exactly two possible measures of angle ACB:
D is along side BC. Line BE and AD are the angle - Algebra …
Let angle ABC be 2x degrees Let angle BAC be 2y degrees Then the angle we are to find, ACB, is (180-(2x+2y)) degrees. Angles EBA and EBC are each x degrees; angles DAB and DAC are each y degrees. Angle BEC is 75 degrees, so angle BEA is 180-75=105 degrees; angle ADC is 84 degrees, so angle ADB is 180-84=96 degrees. In triangle ABD, 96+2x+y=180 [1]

Jan 8, 2021 · Answer: 50. Explanation: abc has to be 110. triangle angles add to 180. 110+20=130. 180-130=50
Given: ΔАВС, m∠ACB = 90° CD ⊥ AB, m∠ACD = 60° BC = 6 cm …
Jan 31, 2018 · 1. If m∠ACB=90° and m∠ACD=60°, then m∠BCD=30°. Consider right triangle BCD. BC is its hypotenuse. The leg that lies opposite to the 30° angle is half of hypotenuse, then BD=3 cm. By the Pythagorean theorem, 2. Consider right triangle ACD, m∠ACD=60°, then m∠CAD=90°-60°=30°. Thus, the leg CD is opposite to the hypotenuse AC and . 3.
Information about triangle ABC is given below. Angle ACB= 59 …
Nov 25, 2023 · The student provided information about triangle ABC: Angle ACB is 59 degrees, side AB is 61mm, and side AC is 70mm. To calculate the two possible sizes for angle BAC, we make use of the Law of Sines. The Law of Sines states that for any triangle, the ratio of the length of a side to the sine of its opposite angle is the same for all three sides ...
What is the measure of ACB? - brainly.com
May 21, 2018 · In triangle ABC, we already know the measure of angle B (given in the diagram), so we can subtract the measures of angles A and C from 180 to find the measure of angle ACB. Let's say angle A measures x degrees and angle C measures y degrees. Then, we have the equation x + y + 40 = 180. Solving for x, we subtract 40 from both sides to get x + y ...
If angle ACD measures 45 degrees, then angle ACB measures
May 8, 2023 · The measure of angle ACB is 45 degrees. How to determine the angle. In order to determine the specified angle, we need to take note of the following; A rectangle has four sides; It has four equal angles; Each of the interior angles measures 90 degrees; the diagonal bisects the angle into two equal halves; Angle at right angle is 90 degrees
Accurately construct triangle ABC using the information below. AB …
Jun 9, 2023 · The calculated size of the angle ACB is 68.10 degrees and the triangle is attached. How to determine the measure of the angle ACB. From the question, we have the following parameters that can be used in our computation: AB = 7 cm. AC = 4 cm. BAC = 80 degrees. The measure of the length BC is calculated as. BC² = AC² + AB² - 2 * AC * AB * cos(BAC)
