Answer:
The measure of angle B is 50
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
not enough information to prove they are congruent. the postulates need 3 things that are congruent, unless it's a right triangle, you only need two. However, in this image, they are not shown to be right triangles.
Answer:
y = - 4x - 3
Step-by-step explanation:
- 2y - 8x = 6 ( add 8x to both sides )
- 2y = 8x + 6 ( divide through by - 2 )
y = - 4x - 3 ← in slope- intercept form
Answer:
Here are 5 (2,4), (3,6), (1,2), (4,8), (5,10)
Step-by-step explanation:
Answer:
A. 220
Step-by-step explanation:
To find the total surface area of a square pyramid, you have to find the area of the base and all of the sides and add them together.
To find the area of the base:
Since the base is a square, all we have to do is multiply the length by itself.
10 * 10 = 100
The base is 100 square centimeters
To find the area of the sides:
Since the sides are triangles, we have to multiply the length times the height and divide it by 2.
10 * 6 = 60
60/2 = 30
The area of one side is 30 square centimeters
To find the total surface area:
Add the area of all 4 sides and the area of the base together to find the total surface area.
4(30) + 100 = surface area
120 + 100
220 = surface area
The surface area is A. 220 square centimeters.
