What is the value of x?

Greeley [361]

Answer:

x = 75

Step-by-step explanation:

Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. To solve, we will set up a proportion and solve.

A proportion is two equal ratios set equal to each other. We form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). Out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

$\frac{little}{big} =\frac{little}{big}$ .

$\frac{42}{42 + 63}=\frac{50}{50+x}$

$\frac{42}{105}=\frac{50}{50+x}$

To solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

$42(50+x)=105(50)\\2100 + 42x =5250 \\ 42x = 3150 \\\frac{42x}{42}=\frac{3150}{42} \\x =75$

Please help me answer this will give brainlst

VladimirAG [237]

Answer:

17° and 73°

Step-by-step explanation:

For two complementary angles, the sum of angles is equal to 90 degrees.

Let other angles = x

First angle = 5+4x ...(1)

ATQ,

5+4x+x=90 ...(2)

Equation (1) and (2) shows the equations for the given problems.

5+5x=90

5x = 85

x = 17°

Other angle = 17

First angle = 5+4x

= 5+4(17)

= 73°

So, the other two angles are 17° and 73° respectively.
