All angles of a triangle *always* equal to 180*. R=120 and two angles on a flat line also equal to 180. So, *180-120=60*. So *60+60+60*, all the angles of the triangle, equals to 180. So angle x=60.

3.) What is the measure of angle a in the triangle below?<br> a<br> 50°

Rom4ik [11]

40°

Step-by-step explanation:

∠ACB = ∠DCE ( vertically opposite angle )

Now...

a + 90° + 50° = 180° ( the sum of interior angle of triangle is 180° )

a + 140° = 180°

a = 180° - 140°

a = 40°

hence the value of a is 40°

7.935 x 10 to negative 5 power

Effectus [21]

Answer:

0.00007935

Step-by-step explanation:

7.935 x 10 to negative 5 power can be written as:

7.935 x 10^(-5)

$7.935*10^{-5}\\\frac{7.935}{10^5}$

A trick to finding 10 to the x power, x is the number of 0's. So 10^5 = 100000

$\frac{7.935}{100000}\\$

When dividing by tens, move the decimal to the left by the amount of 0's

So our answer is 0.00007935
