Answer:
578
Step-by-step explanation:
118
+560
answer:678
678-100=578
X+5=2x-7
x=12
y=12+5
y=17
(12, 17)
Angle 1 = 30°
Angle 2 = 90°
⇒ Angle 3 = 60°
So, it's right triangle. We can set the length of one side and get all other sides.
So, we have 1 triangle. If there are 2 or more triangles with the same data, all the triangles will be congruent because of : <span>Two triangles are </span><span>congruent if </span>"<span>ASA: Two interior angles and the included side in a triangle have the same measure and length, respectively, as those in the other triangle</span><span>.</span>"
8/x^4
I multiply to get everything out of the Parentheses.
Then a lot more steps
But the answers is 8 over x to the power of 4
