Answer:
30
Step-by-step explanation:
A triangle has a total degree of 180. We already have 150(from the 60 and the right angle) 180-150 is 30
Answer:450
Step-by-step explanation:
first subctract then add
Answer:
To find the area of she shaded part we first need to find the total of the area.
L x W
8 x 5 = 40 is the total area
Now we need to find the area of the non - shaded part
Since it is a square all sides are equal the short lines sticking from the sides indicate that
2 x 2 = 4
Now we subtract the total area from the non shaded area.
40 - 4 = 36
In a triangle, the three interior angles always add to 180°
m∠R + m∠S + m∠<span>T = 180
</span><span>(2x+10) + (2x+25) + (x-5) = 180
</span>2x+10 + 2x+25 + x-5 = 180
5x + 30 = 180
5x = 150
x = 30
