Answer:
x=4
Step-by-step explanation:
4x+7=23
4x=23-7
4x=16
x=16÷4
x=4
We have been given that in a right triangle, the measure of and the side opposite to the measure of theta is 6.5 cm long. We are asked to find the length of adjacent side to the angle theta.
We know that tangent relates opposite side of right triangle adjacent side.
Therefore, the length of adjacent side to angle theta is approximately 6.97 units.
The angles of a 4 sided shape always add up to 360.
y + x + 190 - y + 70 = 360
x + 190 + 70 = 360
x + 260 = 360
x = 100
You must know that the sum of interior angles is 180°. We also know that AC and BA are congruent which means angles B and C are also congruent. To find x we can assume 25=5x. Which makes x=5, and angle C=25°.
Then we can add all the angles to find y and A. 25+25+(3y+70)=180. Then solve for y and then solve for angle A.
