Answer:
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees.
One of the angles of a triangle measures d°, another measures (3d)°, and the third measures (5d + 54)°. The equation becomes
d + 3d + 5d + 54 = 180
9d + 54 = 180
9d = 180 - 54
9d = 126
d = 126/9
d = 14
First angle is 14 degrees
Second angle is 3 × 14 = 42 degrees
Third angle is 5 × 14 + 54 = 124 degrees

Step-by-step explanation:
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
