Answer:

85 degrees

Step-by-step explanation:

So we can see that the two angles form a "c." This c indicates that it is a same side interior angle. Same side interioir angles are equal to 180 degrees. So, set both the expressions to 180.

x+90+x+100=180

2x+190=180

2x=-10

x=-5

Substitute in the value for x

-5+90=85

I hope this helps!

Answer:

$c= \sqrt{41}$

Step-by-step explanation:

$a^{2} +b^{2} =c^{2} \\4^{2} + 5^{2} = 16 + 25 = \sqrt{41} = c$

If x = 8 units, y = 3 units, and h = 10 units, find the area of the trapezoid shown above using decomposition.

kondaur [170]

If by decomposition you mean breaking it ino parts then

break it itno 2 triangles and 1 rectangle

left to right

triangle with base y and height h
h=10
y=3
area of traignel=1/2bh
aera=1/2(10)(3)
area=5(3)
area=15

rectangel of legnth x and height h
area=legnth timwe width
x=8
h=10
area=8 times 10
aera=80

last triangle
should be same as other sinces same base (y) and same height (h)
15

add
15+80+15=120

I plugged this into photo math, but apparently I have to pay to find out how to get the answer. can you guys help me out?

Photo math is charging? We don't need it. We factor the difference of two squares.

$\dfrac{5t^2-500}{t+10} = \dfrac{5(t^2- 100)}{t+10} = \dfrac{5(t-10)(t+10)}{t+10} = 5(t-10) = 5t-50$
