Triangle OPQ with vertices O(-9,6),P(-5,7), and Q(-6,9) drawn in a triangle. Whst is thecarea in square units of the OPQ

answer: i think the answer is etheir c or d but i don't know which one but have a good day!

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

-1
