PLZ I NEED HELP UNDERSTANDING THIS SOMEONE PLZ HELP ME
tatuchka [14]

Answer:

90

Step-by-step explanation:

180°-104°=76°( sum of angles A and B)

76°÷2=38°

x=38°

Bcuz it is an isosceles triangle ( a triangle with 2 equal sides). So, angle B and A are equal. thats why 76° must be divided by 2.

180°-104°=76°(angles on a straight line)

180°-76°=104° (sum of angle A and C)

104°÷2=52°

y=52°

it is also an isosceles triangle.

x+y=38+52=90°

Plot the point (−12, −52) on the coordinate plane.
irinina [24]

Answer:

Step-by-step explanation:

-12 goes on the x axis (the line that goes ⇄), and because it's negative, it will go to the right.

start from that point (-12 on the x axis) and start going down till you reach -52 on the y axis (the line that goes ⇅)

so it should end up in the bottom left part of the graph
