Equation practice with angle

Mathematics
1 answer:
cestrela7 [59]3 years ago
7 0

Answer & Step-by-step explanation:

AOC is a straight angle. Straight angles have a measurement of 180°. ∠AOB and ∠BOC make up ∠AOC. So this measn that when you add ∠AOB to ∠BOC, then they should have a sum of 180°.

<em>m∠AOB + m∠BOC = 180°</em>

<em>m∠AOB = 3x + 142</em>

<em>m∠BOC = 6x + 29</em>

Now, set up the equation.

<em>3x + 142 + 6x + 29 = 180</em>

<em>9x + 171 = 180</em>

<em>9x = 9</em>

<em>x = 1</em>

Now that we have the value of x, then we can find the measurement of ∠BOC.

m∠BOC = 6(1) + 29

m∠BOC = 35

So, the measurement of ∠BOC is 35°

Two cars leave towns 760 kilometers apart at the same time and travel toward each other. One car's rate is 12 kilometers per hou
zaharov [31]

Answer:

89 km/hr

Step-by-step explanation:

Distance = Rate(speed) × Time

D = R × T

T = 4 hours

One car's rate is 12 kilometers per hour less than the other's.

Hence:

First's car's rate = r × 4 = 4r

Second car's distance = (r + 12) × 4 = 4r + 48

4r + 4r + 48 = 760

8r + 48 = 760

8r = 760 - 48

8r = 712

r = 712/8

r = 89 km/hr

The rate of the slower car is 89 km/hr
