Which pair of triangles must be similar?
a) triangles 1 and 2 each have a 35° angle.
b) triangles 3 and 4 are both isosceles. they each have a 40° angle.
c) triangle 5 has a 30° angle and a 90° angle. triangle 6 has a 30° angle and a 70° angle.
d) triangle 7 has a 50° angle and a 25° angle. triangle 8 has a 50° angle and a 105° angle.

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu

$205,000 here you go i had to guess it but i got it correct so yeah
