Answer:
should be 30
Step-by-step explanation:
triangles have 180°
if x is 30
2x is 60
the other angle is 90
add those all together and you get 180°
Answer:
The answer is 121
Step-by-step explanation:
So basically it's like dividing 4 from 4 and you get 1
Then 8 from 4 and it would come out as 2
And divide 4 once more from 4 and get 1 again
4÷4=1
8÷4=2
4÷4=1
Then out the answers together and you got 121
Answer:
Step-by-step explanation:
a) Set up the variables:
Let <u>x</u> represent the width; Then <u>2x</u> will represent the length.
b) What is the equation that represents the above situation?
<u>Use perimeter formula:</u>
As we set up w = x and l = 2x, and we know that the perimeter is 30 cm, we can build an equation by substituting the values we know or set up:
c) solve the equation
- 30 = 2( 2x + x)
- 30 = 2(3x)
- 30 = 6x
- x = 30/6
- x = 5
d) the length and width are?
- The width is 5 cm and the length is twice the width, 5*2 = 10 cm
Answer:
area = 147.03 cm²
Step-by-step explanation:
area =16.9 x 8.7 = 147.03 cm²
Step-by-step explanation:
2x+4 +3x = 2x +2 +1
4+x= 2x+3
4-3=2x-x
1=x
x=1
