Answer:
divide 90 and 30 to see what you got
Step-by-step explanation:
Remote interior angles are the two angles that are not supplementary with the exterior angle of a triangle.
<c and <a are the remote interior angles of <y
<a and <b are the remote interior angles of <d
In a tight triangle, one angle measures 90°. All triangles add up to 180° according to the Triangle Sum Theorem. Using the measure of 50°, we can find the measure of the other angle.
90+50=140
180-140=40
The measure of the other angle is 40.

Answer:
English
Step-by-step explanation:
Let's use the "elimination by addition/subtraction" method to solve this system for x and y.
<span> -8x=72-16y
4x=-92+16y <= Mult. all 3 terms by 2: 8x = - 184 + 32y
Now combine the following, column by column:
</span><span> -8x= 72-16y
</span>8x = - 184 + 32y
-----------------------
0 = -112 + 16y. Solving for y, 16y = 112, and y = 7.
Now subst. 7 for y in either of the original equations and calculate x:
<span>4x=-92+16(7) => 4x = -92 + 112 = 20. Then x = 5.
Solution is 5, -7 (or, better written) (5, - 7).</span>
