Answer 1

A. 26 degrees
B. 48 degrees
c. 52 degrees
d. 64 degrees

Answer 2

your triangle is an isosceles triangle, so the angles at the base NL, has to be congruent. Then we can write:
\[7x + 8 = 9x - 8\]

Answer 3

subtracting 7x from both sides, we get:
\[\begin{gathered}
8 = 2x - 8 \hfill \\
\hfill \\
2x = 16 \hfill \\
\end{gathered} \]
please solve for x

Answer 4

8

Answer 5

ok! so the measure of angle OLM is:
9*x-8= 9*8-8=64 degrees

Answer 6

so is it a b c or d @Michele_Laino

Answer 7

the requested measure x, is given by the subsequent equation:
\[\begin{gathered}
x + 90 + 64 = 180 \hfill \\
x + 154 = 180 \hfill \\
x = 180 - 154 = ...? \hfill \\
\end{gathered} \]

Answer 8

more precisely, the measure of the amplitude of the angle OML is:
180-155=...? degrees

Answer 9

26

Answer 10

correct!
