Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
Let's first establish that the shape is a triangle meaning that the following formula is applicable as displayed below:
Angle sum of a triangle = 180°
As well as this, the shape is an equilateral triangle meaning that each angle of the triangle is equivalent in value. Also, the following formula is also applicable as displayed below:
Each angle of an equilateral triangle = the same value
Therefore:
Each angle of an equilateral triangle = angle sum of a triangle ÷ no. of angles in a triangle = 180° ÷ 3 = 60°
Based on this, the following is applicable:
2x - 4 = 60°
2x = 60 + 4
2x = 64
x = 64 / 2
x = 32°
ANSWER:
Therefore, the answer is:
The value of ( x ) is 32°

Answer:
8x+8y
Step-by-step explanation:
The answer is B because if you get 5 on the first test then you will have 10 already. if you get at least 1 point on the second then you will have 11 or higher. since the 1st is doubled then the shaded region will retreat by 2 squares for every point less then the maximum you get on the first test.
Area of triangles: 1/2 x b x h
area of square: l x w
Triangle
1/2 x 7 x 4= 14, but there are 3 of them so 42
Square: 7 x7 = 49
49 + 42 = 91
Awnser
y=13
Step-by-step explanation:
-3x+2y=56
-5x-2y=24
so first we want to get rid of one variable, in this example we dont need to multiply because the y's cancel out
so we have
-8x=80
x=-10
now plug in x into an original equation
-3(-10)+2y=56
2y=26
y=13
hope that helps
