Answer:

Top right ?- 60

? above 64- 64

Bottom left- 45

Step-by-step explanation:

Triangles equal 180.

The question mark above 64, the 64 and ? are congruent so the question mark is 64.

The question mark in top right, add 64+56=120. Since triangles equal 180, subtract 180-120=60

The question mark in bottom left, add 64+71=135. Since triangles equal 180, subtract 180-135=45

Hope it helps!

What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?

AnnZ [28]

The value of n in given proportion is 16

Solution:

We have to find the value of "n" in the proportion

Given proportion is:

$\frac{n}{28} = \frac{4}{7}$

We can solve the above proportion by cross-multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable

$->\frac{n}{28} = \frac{4}{7}$

$-> 7 * n = 4 * 28$

$-> n = \frac{4 * 28}{7}$

$-> n = 4 * 4 = 16$

Thus the value of n in given proportion is 16
