Answer:
Step-by-step explanation :
Ratio = 3x : 4x
<h3>
Sum of angle of a quadrilateral = 360</h3><h3>
Therefore, 140+80+3x+4x = 360</h3><h3>
220+7x = 360</h3><h3>
7x = 360-220</h3><h3>
x= 140/7</h3><h3>
x=20</h3><h3>
3x= 3×20=60</h3><h3>
4x=4×20=80</h3>
Answer:
2
Step-by-step explanation:
We know that the opposite sides of a parallelogram are equal so:
25x+1=7x+37
18x=36
x=2
A net is basically a flattened out 3D solid. If you fold all the sides up, you would end up with the 3D model.
Answer:
Part 1) m∠EFG=94°
Part 2) m∠GFH=86°
Step-by-step explanation:
we know that
m∠EFG+m∠GFH=180° -----> by linear pair (given problem)
we have
m∠EFG=3n+22
m∠GFH=2n+38
substitute the values
(3n+22)°+(2n+38)°=180°
Solve for n
(5n+60)=180
5n=180-60
5n=120
n=24
<em>Find the measure of angle EFG</em>
m∠EFG=3n+22
substitute the value of n
m∠EFG=3(24)+22=94°
<em>Find the measure of angle GFH</em>
m∠GFH=2n+38
substitute the value of n
m∠GFH=2(24)+38=86°
