Answer: green angle = 76 degree
Solution:
We can use interior angle properly of a triangle to find it.
Exterior angle = sum of interior angles
So, 116 = 4x + (7x + 6)
11x + 6 = 116
11x = 116 - 6
11x = 110
x = 110/11 = 10
So, angles = 4 x 10 = 40
7 x 10 + 6 = 70 + 6 = 76
Green angle: 76 degree
Answer:
C: Lucy can type 120 words in 4 minutes

30 represents words so Lucy can type 120 words per 4 minuets
Answer:
Step-by-step explanation:
<u>GIVEN:
</u>
To find the missing number in the proportion, you have to isolate it the term of x from one side of the equation.
First, thing you do is switch sides.
Multiply by 21 from both sides.
Solve.
Multiply the numbers from left to right.
Use the order of operations.
PEMDAS stands for:
- Parentheses
- Exponents
- Multiply
- Divide
- Add
- Subtract
- <u>Therefore, the final answer is x=24.</u>
