Answer:
Step-by-step explanation:
x + x + 65 °+ 25° = 180° ( being sum of angles of triangle )
2x + 90° = 180°
2x = 90°
x = 45
now
<A = 45°
< B = x + 65° = 45 °+ 65 °= 110°
< C = 25°
Hope it helps :)
I believe your answer is C
Answer:
9x + 8.
Step-by-step explanation:
2(x - 3) + 7(x + 2)
= 2x - 6 + 7x + 14
= 2x + 7x - 6 + 14
= 9x + 8.
Hope this helps!
Answer:
8 inches
Step-by-step explanation:
A rhombus is a four sides quadrilateral with the four sides equal in length
A rhombus has 4 equal sides and the diagonal bisect at right angles
Adjacent sides = 9/2 = 4.5
we are to determine the value of the hypotenuse given the adjacent side and angle (108/2) = 54
Cos 54 = adjacent / hypotenuse
0.58778 = 4.5 / hypotenuse
hypotenuse = 4.5 / 0.58778
=7.6559
= 8 inches
