Answer:
51
Step-by-step explanation:
since 1 = 39 degrees, it'd be complementary if you were to open it up if it were a C, it would be 90. So since its this way, i believe you would take 39 and do 90 - 39 to get your answer. Im sorry if this is wrong but i hope it helps you!!
X is 5
Y is 25 and then you just multiply by 3 each time
Answer:
The answer to your problem is B.
step 1
Find the measure of angle 1
REmember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle ABC
90+58+<1=180
148+<1=180
<1=180-148
<1=32 degrees
step 2
Find the measure of angle 2
we know that
<2=<1 -----> bt vertical angles
so
<2=32 degrees
step 3
Find the measure of angle 3
REmember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
In the triangle CDE
32+108+<3=180
140+<3=180
<3=180-140
<3=40 degrees
