Answer:
90
Step-by-step explanation:
9^2 = 81 and 3^2 = 9
81 + 9 = 90
Answer:
L = 186
Step-by-step explanation:
84 - 60 = 24
210 - 24 = 186
Answer:
w = sa
Step-by-step explanation:
Given
s = 
( multiply both sides by a to clear the fraction )
sa = w
Hint: the sum of the angles is equal to 180 in a triangle. could you make an equation to use that?
3x+13, 7x+2, and 75 are the three angle values. They will sum up to 180.
Steps:
We set the equation to:
3x+13+7x+2+75=180
We can combine some terms
10x+90=180
Then, we isolate x
10x=90
And we divide by 10
x=9
Great! but we are not done yet. We want the measure of angle A, so we need to plug x back into the equation for angle a
3(9)+13
Multiply
27+13
Add
40
Answer: 3/5
Step-by-step explanation:6/10 6 divide by 2 and 10 divide by 2
