Answer:

x = 45

Step-by-step explanation:

The 3 angles of a triangle add up to 180

<a + <b + <c = 180

substitute what you know

55+ 80 + <c = 180

combine like terms

135 + <c = 180

subtract 135 from each side

<c = 180 -135

<c = 45

x = 45

What number could replace kkk below? \dfrac{k}{100} = \dfrac{1}{10} 100 k = 10 1 start fraction, k, divided by, 100, end fra

Ivanshal [37]

Answer:

Step-by-step explanation:

Given the equation;

$\dfrac{k}{100} = \dfrac{1}{10}$

We are to find the value of k.

Cross multiply;

$\dfrac{k}{100} = \dfrac{1}{10} \\10 \times k = 100 \times 1\\10k = 100\\$

Divide both sides by 10

$10k/10 = 100/10\\k = 10$

Hence the value of k is 10
