The measures of two interior angles of a triangle are 45° and 53°. What is the measure of the third interior angle of the triangle?

82°

Step-by-step explanation:

Sum of interior angles of a triangle is 180°

Add the two given angles and subtract it from 180 to get the third angle.

180-(45+53) = 82°

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
