Answer:
X will be equal to 36 degrees.
Step-by-step explanation:
A full angle of a pentagon is 108 degrees. A line connecting from a base corner to on the opposite side splits the pentagon into a rhombus and a triangle. In the triangle, two corners will be the same side, while the largest corner will be 108 degrees.
180-108 = 72
72 / 2 = 36
Therefore, x is equal to 36 degrees.
Hopefully this helps :)
If y = x^2 + 2x and y = 3x + 20
<span>Then </span>
<span>x^2 + 2x = 3x + 20 </span>
<span>x^2 - x - 20 = 0 </span>
<span>(x - 5)(x + 4) = 0 </span>
<span>x = 5, - 4 </span>
<span>For x = 5, y = 3(5) + 20 = 35 </span>
<span>For x = - 4, y = 3(-4) + 20 = 8 </span>
<span>(5, 35), (-4, 8)</span>
Answer:
1,5
Step-by-step explanation:
-4• 1/4 + (5•1/2)=
-4/4 + (5/2)
-1+2,5=
+1,5
