Answer:
∠A = 99°
Step-by-step explanation:
Complementary angles sum to 180°, thus
∠A + ∠B = 180 ← substitute values
2x - 23 + x + 20 = 180
3x - 3 = 180 ( add 3 to both sides )
3x = 183 ( divide both sides by 3 )
x = 61
Hence
∠A = 2x - 23 = (2 × 61) - 23 = 122 - 23 = 99°

Can you give me a picture of the question? Or be more specific?
Answer:
a is the ans;8/15
Step-by-step explanation:
we have tanb = p/ b
so,by taking reference angle b we get,
p=8 and b= 15.
therefore; tanb=8/15
