Answer:

m<ABC=94°

m<BCD=25°

m<ACB=43°

Step-by-step explanation:

To find <mBCD

m<ABD=133°, so m<CBD=133° too.

A triangle is equal to 180°.

22°+133°=155°

80°-155°=25°

To find <mACB

You first need to know triangle ACD measurements.

m<ADC=44° (22°+22°)

Then you take the two 25 and add them.

25°+25°=50°

50°+44°=94°

180°-94°=86°

86°÷2=43°

To find m<ABC

43°+43°=86°

180°-86°=94°

Solve for x in the equation p(m+qx)=rx+n

katrin [286]

$p(m+qx)=rx+n\\\\\implies pm+pqx = rx+n\\\\\implies pqx-rx = n-pm\\\\\implies x(pq -r) = n-pm\\\\\implies x = \dfrac{n-pm}{pq-r}$

Kayla ran from her home to a beach at a speed of 6 meters per second. the distance from her home and the beach was 756 meters. A

german

Looking at the units, 756 meters divided by 6 m/s will give you the seconds that you need.

So for A) 756/6 = 126

For B, you take the answer from A, and subtract 18 seconds, which would make it 108. Then you take the distance, 756 and divide by 108, that will be the speed.
