∠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°

Answer:
-36
Step-by-step explanation:
‐13−23= ‐13 + (-23) = -36
Both 13 and 23 have negative sign. So if two numbers have the same sign, we have to add and put the same sign.
Answer:
3131x+1
Step-by-step explanation:
Make equation simple
5x times 5x times 5x times 5x times 5x +x+1
Solve
5 times 5 times 5 times 5 times 5 = 3125
x times x times x times x times x times x = 5x
3125+5x=3130x
Now you might be thinking you cant add x but here your can because it is just broken apart
now add x+1
3131x+1
