(Angle/triangle problem 25points) What is the value of X?

Mathematics
1 answer:
Serhud [2]3 years ago
3 0

Answer:

x = 5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles in the triangle and equate to 180, that is

10x - 4 + 8x + 3 + 91 = 180

18x + 90 = 180 ( subtract 90 from both sides )

18x = 90 ( divide both sides by 18 )

x = 5

What is the sum of 4.9 × 102 and 6.8 × 103?
dusya [7]

Answer:

The sum is

7.92\times 10^3

Step-by-step explanation:

We want to add

4.9\times 10^2 and 6.8\times 10^3

The sum of these two numbers is:

4.9\times 10^2 +6.8\times 10^3

This is the same as:

4.9\times 100 +6.8\times 1000

490 +6800=7290

We rewrite 7290 in standard form to get;

7.92\times 10^3

The measure of two adjacent sides of a rectangle is in the ratio of 11:10. If the perimeter of the rectangle is 84 cm, then find
anygoal [31]
A ratio of 11x to 10x

Where x is a number to keep the ratio the same.

Perimeter = 84

Perimeter = 2 (Length + breadth)

84 = 2 ( 11x + 10x)
84 = 2(21x)
21x = 42
x=2

So that means the actual length of the sides would be:

11 x 2 : 10 x 2
22 : 20

So that means the length can be 22, and the breadth will be 20.
Or the length is 20, and the breadth is 22.
