Please. Help need for son

x=76

Step-by-step explanation:

All of the inside angles of a triangle add up to 180

so: 180 - 28 =152

152/2 = 76

76

Step-by-step explanation:

An isosceles triangle is where 2 angles will be equal. All angles equal to 180. 180 - 28 = 152

152 divided by 2 = 76

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
