Answer:
x = 14
Missing angles: 33° and 57°
Step-by-step explanation:
(2x + 5) + (3x + 15) = 90° (complementary angles)
Add like terms
5x + 20 = 90
5x = 90 - 20
5x = 70
x = 70/5
✔️Plug in the value of x to find each missing angle:
2x + 5 = 2(14) + 5 = 33°
3x + 15 = 3(14) + 15 = 57°
B and D
x=14
First bring the 6 to the other side and then bring the 4x to the other side to have 5x-4x=6+8 and combine the like terms and x equals 14.
, which c approximately equals 153.44. So Line AB ≈ 153.44 meters.
