Answer:
8 + d = 43
Step-by-step explanation:
Hello,
let's say x is a certain number
10*x+9+2x=633
12x=624
x=52
Proof:
529+104=633
49 would be in the next space after 42 because this sequence is counting by 7s
Answer:
<h3>
m∠A = 46°</h3>
Step-by-step explanation:
∠A and∠B being complementary means m∠A+m∠B=90°
m∠A = (4x+6)° and m∠B = (4x+4)°
so:
4x+6 + 4x+4 = 90
8x + 10 = 90
8x = 80
x = 10
m∠A = (4•10+6)° = 46°
