Answer:

180 degrees in a triangle

180 - 78 - 47- 61 = -6

2X = -6

-6/2 = -3

-3 + 47 = 44

-3+61= 58

78 + 58 + 44= 180

A = 44 degrees

Find the value of x. A.18 B.15 C.16 D.19 PLEASE HELP!!!!!

In-s [12.5K]

Answer:

x = 19

Step-by-step explanation:

123°+3x = 180°

3x = 180°-123°

3x = 57

x = 57/3

x = 19

The reason why we use 123° + 3x = 180° because both are adjacent angles. Adjacent angles add up to 180°

Leviafan [203]

Answer:

$\displaystyle a=\frac{d}{.5*t^2}$

Step-by-step explanation:

Equation Solving

We are given the equation:

$d=.5*a*t^2$

It's required to solve it for a.

Swap sides to have the letter on the left side:

$.5*a*t^2=d$

Divide by $.5*t^2$ :

$\mathbf{\displaystyle a=\frac{d}{.5*t^2}}$
