Answer:
19
Step-by-step explanation:
Answer:
3x=43
x=43÷3
x=14.35(appro)
Step-by-step explanation:
First divide 3 by 43
THEN you will find the Answer
If it’s a triangle then it has to equal 180
so 48+54+x=180
48+54=102
180-102=x
x=78
Yep, sure. Which question?
Answer:
x = 16
∠A = 39
∠B = 54
∠C = 87
Step-by-step explanation:
Make a equation of all of the angles added together is equal to 180 since the angles of a triangle added together is 180
(4x-10)+(2x+7)+(7x-25)=180
combine like terms
4x+2x+7x-10+7-25 = 180
13x-28=180
solve for x
13x=208
x = 16
plug in x to find the measure of the angle
∠A = 2(16) + 7 = 39
∠B = 4(16) - 10 = 54
∠C = 7(16) - 25 = 87
Add them together to double check your answer
39 + 54 + 87 = 180
hope this helps
