(predicted value - exact value)/exact value * 100
(31 - 34)/34 * 100 = 8.8%
We know that
scale factor=measure larger triangle/measure smaller triangle---->18/12
scale factor=1.5
so
measure larger triangle=scale factor*measure smaller triangle
for the leg in the smaller triangle equal to 5
measure larger triangle=1.5*5-----> 7.5
the answer is
7.5
Check out the picture I've got the full explanations on there
Hope it's clear
2x+50 + 3x= 90 degrees
5x +50 = 90
5x =40
x=8
Angle1= 2(8) +50= 66
Angle2= 3(8)=24
66+24+90= 180
Hey!
------------------------------------------------
They already give us the slope, so we can solve the y-intercept.
We can use (3, -2).
y = 8x + b
-2 = 8(3) + b
-2 = 24 + b
-2 - 24 = 24 + b - 24
-26 = b
------------------------------------------------
Hence, the answer is
------------------------------------------------
Hope This Helped! Good Luck!
