Answer:
x = 52.5
Step-by-step explanation:
The triangle on the left has 2 congruent sides, thus is isosceles
The base angles of an isosceles triangle are also congruent, thus
x = 
= 
= 52.5
so
6s+2l = 28
4s+5l= 37
eliminate 6s+2l=28 by dividing all numbers by 6
u get s= -1/3 l + 14/3
49-1/3l=14/3) + 5l =37
L=5
s= -1/3(5) + 14/3
s=3
l=5
Answer:

Step-by-step explanation:
6. It is on Y:4 & X:0 and skipped on, Y:14 & X:5
7. It is on Y:4 & X:0 and skipped on, Y:14 & X:5
Answer:
<h3 />
Step-by-step explanation:
20% of 32 is 6.4
Isoceles triangles have one pair of congruent base angles opposite their congruent sides. Also, the angles in a triangle add up to 180°. Therefore, we can set up this equation:
100 + x + x = 180
(we know it's not the 100° angle that has a congruent match because that would cause the total angle measure to go above 180°)
100 + 2x = 180
Subtract 100 from each side.
2x = 80
Divide by 2.
x = 40°
Both of the other angles would be 40°.
