The length of a rectangle is four times its width. if the perimeter of the rectangle is 80yd, find its length and width.

Vedmedyk [2.9K]

The length is 8. the width is 32.

32(2) = 64

8(2) = 16

64+16 = 80

So the length would be 8 and the width would be 32 since it's 4 times the length.

Hope this helped!

This is a 30-60-90 triangle. a What is the measure of x? Х 43 X= = [ ?

kherson [118]

Answer:

See below:

Step-by-step explanation:

Hello! I hope you are having a nice day!

We can solve this problem in two steps; solving and theory.

I'll go and start off with the theory part!

Theory

We know that in geometry there are many types of triangles that have various different angles. With that, there are a few special triangles that people have made formulas for, one being a 30, 60, and 90 degree triangle.

The theorem states that the hypotenuse is $2x$ , the side opposite to 60 degrees is $x\sqrt{3}$ , and the bottom is $x$ .

Solving

We can solve this problem in a step, we just need to know what the theorem said and implement it here, since we know the values of the sides of the triangle, we can solve it by finding out the opposite side and applying the theorem rules.

If we look at the graph, we can see that the $x$ part of the side opp. of 60 degrees is 4, that means that $x$ would be double of 4, which is 8.

Therefore your answer would be: $x=8$

Cheers!

2 angles measure 40 degrees each, what does the third angle measure? what type of triangle is it?

zimovet [89]

Answer:

Part a): 100 degrees

Part b): Isosceles Triangle

Step-by-step explanation:

Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.

180 - 80 = 100

Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.
