I assume that you want the measurement of angle A
A + (A + 38) = 90
angle A + (38 more than angle a) = are complementary
2A = 52
A = 26
Hope this helps. If it did, consider making it Brainliest!
A. the polynomial can then be factored to (x+10)(x+2).
I dunno I rlly don't know like seriously I'm in 7th
Answer:
14 yd
Step-by-step explanation:
The cross section is a triangle with a height of 19 and a base of x
Area of a triangle = bh/2
133 = 19x/2
266 = 19x
x = 14
