4(4m -3) + -1m(m + -5) = -52

4(-3 + 4m) + -1(m + -5) = -52
(-3 * 4 + 4m * 4) + -1(m + -5) = -52
(-12 + 16m) + -1(m + -5) = -52

-12 + 16m + -1(-5 + m) = -52
-12 + 16m + (-5 * -1 + m * -1) = -52
-12 + 16m + (5 + -1m) = -52

-12 + 5 + 16m + -1m = -52

-12 + 5 = -7
-7 + 16m + -1m = -52

16m + -1m = 15m
-7 + 15m = -52

-7 + 15m = -52
-7 + 7 + 15m = -52 + 7
-7 + 7 = 0
0 + 15m = -52 + 7
15m = -52 + 7

-52 + 7 = -45
15m = -45

15m ÷ 15 = -45 ÷ 15
m = -3

m = -3

Answer: x = 20 degree
3x = 3×20 which is 60 degree
And the other one is 100 degree
Add all the number 100+60+20 degree is 180 degree
Answer:
Solving
we get 
Step-by-step explanation:
13 squared plus b2 equals 18 squared. What is the answer?
We can write it as:

Now, solving and find value of b
We know that 13² = 169
and 18² = 324
Putting values:

Subtract 169 on both sides

Now, taking square root on both sides

So, solving
we get
