Answer:
x=36
Step-by-step explanation:
the triangle is a right angle triangle divided into 2 at the angle representing 90°. Since the second triangle has two equal sides the angles therefore are also equal, hence
180°-72°=108°
then 108°÷2=54°. ( we divided because the angles are equal.
x=180°-90°-54°
x=36°
Heres a tip, multiply the numbers without any decimals then when done, add how many decimal places there are in total.
Ex:16.28 x 4 = 65.12
1625 x 4 = 6512
1700 + 2029.8x = 9500
2029.8x=9500-1700
x=7800/2029.8
x=3.85
? = 40
8×(40+7) is exactly the same as 8×40 + 8×7
