Answer:
4
Step-by-step explanation:
Make the 10% a decimal
.10
Then multiply it by 40
.10*40
You get 4
Answer:
1 : 15
2: 12
3: 52
4: 27.3
Step-by-step explanation:
For #1:
if line m and n are perpendicular then they will create right angles
Right angles have a measure of 90 degrees
That being said we can find the measure of the missing angle by subtracting the measure of the known angle (75) from 90
so k = 90 - 75
90 - 75 = 15
Hence k = 15.
For #3 ( very similar to #1, only difference is the values of the angles )
so R = 90 - 38
90 - 38 = 52
Hence, R = 52
For #2 and #4
Complementary angles have a sum of 90°
So like the previous questions we can find the measure of the missing angle by subtract the measure of the given angle from 90
∠V = 90 - 78
90 - 78 = 12
Hence ∠V = 12
∠Y = 90 - 62.7
90 - 62.7 = 27.3
Hence ∠Y = 27.3
The answer would be B. because a unit rate is usually equal to one for the sake of conversion
Answer:
Thnx
Step-by-step explanation:
have a great day
Triangles equal 180. The bottom left corner is 90 in this triangle. Add the angles together set equal to 180.
x = unknown angle
90 + 67 + x= 180
157 + x= 180
subtract 157 from both sides
x= 23
ANSWER: x=23
Hope this helps! :)
