Answer:
Pls make it clear I did not understand
2.1
If the number was 2.15, you would round to 2.2 because any place that is 5 or greater rounds up and any place less than 5 rounds down.
.1 is the tenths place
.11 is the one hundredths places
∠1 and ∠2 are complementary.
∠1 + ∠2 = 90°
Question a:
∠1 = 23°
∠2 = 90 - 23 = 67°
Ans: 67°
Question b:
∠1 = x
∠2 = 2x + 3
x + 2x + 3 = 90
3x + 3 = 90
3x = 90 - 3
3x = 87
x = 29
∠1 = 29°
∠2 = 2(29) + 3 = 61°
Ans: ∠1 = 29°, ∠2 = 61°
