The interior angles of a triangle all add up to 180 degrees.
You know two of those angles. They are 26 degrees and 90 degrees. The little square thingy in the corner means that angle is 90 degrees.
Using the info above, you can set an equation for the missing angle INSIDE the triangle. Please keep in mind, the x in this equation does not represent angle L.
26+90+x=180
116+x=180
x=64
Now that we know the missing angle inside the triangle, you can find angle L. Angle L and the angle we just found are supplementary, because they are on a line. Supplementary means they add up to 180 degrees.
So, you can make an equation.
64+L=180
L=116
Angle L is 116 degrees. Sorry for the long answer!
Answer:
a = 8
Step-by-step explanation:
-2a + 2 = -14
-2a = -16
-16/-2 = 8
a = 8
Answer:
y = 3
Step-by-step explanation:
the figure on the right is similar, except the lengths are half as big as the figure on the left. the missing segment, PR, corresponds to FH on the other figure, which is 6. 6/2 = 3, so PR, or y, is 3.
