You need to multiply both numbers inside the parentheses by 5:
5 times x = 5x
5 times 7 = 35
So your answer is B. 5x + 35
Question 3. You divide 5 1/4 by 3/4 then multiply that by 20.
The answer is 140
74 degrees
An angles value is 1/2 of the value of its corresponding arc. Angle x has the corresponding arc of 148, so it’s 148/2 or 74 degrees
Answer:
K=10 H=65
Step-by-step explanation:
To work out K, you need to know that opposite angles are the same, so 5k is the same as 50, 50÷5= 10, so k=10
To work out H, you know that opposite angles are the same so 2h is the same as 130, 130÷2=65 so h=65
Answer:
a = 29
b = 64
c = 87
Step-by-step explanation:
Let the angles be a (smallest), b, and c (largest).
We know that a triangle's angles must add up to 180 degrees, so we can construct the following equations.
a + b + c = 180
c = 3a
b = a +35
With some solving and substitution...
a + (a + 35) + c = 180
2a + c = 145
2a + (3a) = 145
5a = 145
a = 29
and therefore,
b = 29 + 35 = 64
c = 3(29) = 87
