Answer:
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180 so the third angle in the first triangle is 180 - 60 - 40 = 80
The value of x is 40 because given triangles are have two pair of angles that are equal.
Number lines are used to represent numbers and ratios using regular intervals
Nuka can weave 8.75 cm of strip in 5 minutes
<h3>How to determine the length of strip</h3>
Represent the ratio with:
Ratio = Length : Time
From the number line, they can weave 7cm of the strip in 4 minutes.
So, we have:
Ratio = 7cm : 4 minutes
Represent the length of strip made in 5 minutes with x.
So, we have:
x : 5 minutes = 7cm : 4 minutes
Remove the common units
x : 5 = 7cm : 4
Express as fraction
Multiply both sides by 5
Evaluate the quotient and the product
Hence, Nuka can weave 8.75 cm of strip in 5 minutes
