Answer:
45 degrees
Step-by-step explanation:
The angle directly down from the 45 degrees angle that the problem gives, is 90 degrees. 45 + 90 equals 135 and all triangles add up to 180 degrees. To find x take 180 - 135. Or 45.
Answer:
Option A, 50 degrees
Step-by-step explanation:
<u>Step 1: Estimate this angle</u>
<em>Option A, works because looks about the size of 50 degrees</em>
Option B, doesn't work because it is not more than a right angle.
Option C, doesn't work because it is not an obtuse angle.
Option D, doesn't work because there is no way it is 15.
Answer: Option A, 50 degrees
Answer:
x=−8 and y=−4
Step-by-step explanation:
8x−17y=4;−8x+15y=4
add eqn1 and 2
to eliminate x
you will get y=-4
put it zin eqn 1
x=-8
