Answer:
70
Step-by-step explanation:
angles in a triangle= 180
79+35=110
180-110=70
ANSWER
The correct answer is B
<u>EXPLANATION</u>
If we analyse the coordinates carefully, you realize there is a mapping of

This is a reflection in the y-axis.
Since the transformation is a reflection, the shape is preserved. Therefore, the image triangle P'Q'R' of triangle
PQR are congruent.
Answer:
66 in
Explanation:
the circumference can be calculated as:

Where d is the diameter and π is 22/7.
So, replacing the values, we get:

Therefore, the circumference is 66 in.
Answer:
- C. The surface area of the pyramid is multiplied by 100
Step-by-step explanation:
The area is the function of the two dimensions.
If each dimension has changed by 10 times, the the area will change by:
Correct choice is C
Answer:
P = 16x + 8
Step-by-step explanation:
Perimeter of a rectangle
= 2(L + W)
Given
L = 5x + 4 and
W = 3x
Therefore
Perimeter = 2(5x + 4 + 3x)
Rearrange the expression
P = 2(5x + 3x + 4)
P = 2(8x + 4)
Now expand the bracket
P = 2 x 8x + 2 x 4
P = 16x + 8
