The measures of two angles of a triangle are 75 and 62º. Find the measure of the third angle.
13°
c. 470
b. 43°
d. 137
Answer: B 43
Step-by-step explanation:
Well for a triangle it has to be equal to 180 so you would add 75 and 62 to get 137 so you would add each answer to 137 and whichever one equals 180 is the answer therefor stating that the answer is B 43.

Find the area of the shaded region.
help pls
Answer:
1. 50 m
2. 80 cm
Step-by-step explanation:
1. There are 2 triangles, subtract the area of 1 of them from the other.
The triangle that needs to be subtracted: b = 20 m, h = 10 m
A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m
The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150
150 - 100 = 50 c
2. Divide it into 3 parts:
1- 3*4 = 12
2. 7*(4 + 4) = 7*8 = 56
3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12
12 + 56 + 12 = 80 cm

4. The side which is congruent to side AB is, A'B'
5. The angle that is congruent to angle C is C'
6. The translation is 9 units left and 6 units down, so (x,y) becomes (x',y') where x' = (x-9) and y' = (y-6)

a. The translation is 2 units right and 8 units down,
so, P (x,y) to P' (x+2,y-8)

PLZ HURRY! Jenny mixed 4 kg of mixed nuts containing 16% peanuts with 12 kg of mixed nuts containing 40% peanuts. What percent of the new mixture if peanuts?
Answer:
34%
n = new % = Answer
(4kg x 16%) + (12kg x 40%) = (New Percentage(Total kg))
(.16 x 4) + (.4 x 12) = n(4 + 12)
Simplify above to get:
.64 + 4.8 = 16n
.64 + 4.8 = 5.44
5.44 = 16n
Divide both sides by 16
.34 = n
34%
Convert .34 to Percentage by moving decimal to the right 2 times.

Consider this rectangle.
The perimeter is P = 2(3) + 2(6) = 18 cm.
Suppose the dimensions of the rectangle are all multiplied by 4.
The new rectangle would have the dimensions _____
The perimeter of the new rectangle would be _ cm.
The new perimeter will be ___ times as large as the perimeter of the original rectangle .
Answer:
new dimentions = 12, 12, 24, 24
new perameter = 72cm
new perameter will be 4 times as large as the original
Step-by-step explanation:
2(3*4) + 2(6*4) = 24+48 = 72
72/4 = 18
The new rectangle would have the dimensions 12 cm and 24 cm
The perimeter of the new rectangle would be 72 cm
And, The new perimeter will be 4 times as large as the perimeter of the original rectangle .
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The perimeter of rectangle is,
⇒ P = 2(3) + 2(6) = 18 cm.
Now, After multiplied by 4 in all the dimensions we get;
Dimensions are,
⇒ 4 × 3 = 12
⇒ 4 × 6 = 24
Hence, The perimeter of the new rectangle would be;
⇒ 2 (12 + 24)
⇒ 2 × 36
⇒ 72 cm
⇒ 18 × 4 cm
Thus, The perimeter of the new rectangle would be 72 cm
And, The new perimeter will be 4 times as large as the perimeter of the original rectangle .
