Answer:
90
Step-by-step explanation:
90 degree angles are angles with a 90 degree turn
Step-by-step explanation:
<span>22.5+7 (n-3.4)=19.8n
We simplify the equation to the form, which is simple to understand
<span>22.5+7(n-3.4)=19.8n
Reorder the terms in parentheses
<span>22.5+(+7n-23.8)=19.8n
Remove unnecessary parentheses
<span>+22.5+7n-23.8=+19.8n
We move all terms containing n to the left and all other terms to the right.
<span>+7n-19.8n=-22.5+23.8
We simplify left and right side of the equation.
<span><span>-12.8n=+1.3
</span>We divide both sides of the equation by -12.8 to get n.
<span>n=-0.1015625</span></span></span></span></span></span></span>
84!
All the sides are 18,24, and 30. Then the two triangles are 12.
83 1/3 % = 5/6 so
20 = (5/6)x
x = (6/5)(20) = 24
