Find the area of the triangle. check my i need it done now! : ( no one will ive reposted it a few times nowyou!

A = 437 mm²

Step-by-step explanation:

The general formula for the area of a triangle:

A = , where 'b' is the measure of the base and 'h' is the measure of the height

Given the dimensions of the triangle in the picture:

A = = 437 mm²

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

is should be y = 5x
