Answer:

x = 24°

Step-by-step explanation:

What do the sum of all angles in a triangle add up to?

  • The sum of all angles in a triangle add up to 180°.

First, let's find the missing angle of the big triangle (the angle next to 111°).

  • 94 + 41 = 135
  • 180 - 135 = 45°

Now, we can find the value of x given the smaller triangle's angle.

  • x + 111 + 45 = 180
  • x + 156 = 180
  • x = 24

Therefore, x = 24°.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Select the expression that has a value of 96.45
leonid [27]

Given:

Number is 96.45.

To find:

The expression that has a value of 96.45.

Solution:

In option a,

0.9645\times 10^2=0.9645\times 100

0.9645\times 10^2=96.45

In option b,

9.645\div 10^1=\dfrac{9.645}{10}

9.645\div 10^1=0.9645\neq 96.45

In option c,

964.5\times 10^3=964.5\times 1000

964.5\times 10^3=964500\neq 96.45

In option d,

9645\div 10^3=\dfrac{9645}{1000}

9645\div 10^3=9.645\neq 96.45

Therefore, the correct option is a.
