In triangleABC, angle B= 90 degrees, cos(C)=15/17 and AB = 16 what is the measure of Angle A, Angle C and angle AC

Sergeeva-Olga [200]

Answer:

m∠C=28°, m∠A=62°, AC=34.1 units

Step-by-step explanation:

Given In ΔABC, m∠B = 90°, , and AB = 16 units. we have to find m∠A, m∠C, and AC.

As, cos(C)={15}/{17}

⇒ angle C=cos^{-1}(\frac{15}{17})=28.07^{\circ}\sim28^{\circ}

By angle sum property of triangle,

m∠A+m∠B+m∠C=180°

⇒ m∠A+90°+28°=180°

⇒ m∠A=62°

Now, we have to find the length of AC

sin 28^{\circ}=\frac{AB}{AC}

⇒ AC=\frac{16}{sin 28^{\circ}}=34.1units

The length of AC is 34.1 units

Will ran 1 2/3 laps of a 1/4 mile track. How far, in miles, did Will run on that track?

MatroZZZ [7]

Answer:

$\boxed{\frac{5}{12} \ miles}$

Step-by-step explanation:

Will ran = $1 \frac{2}{3} \ of \ a \frac{1}{4} \ miles \ track$

Will ran = $\frac{5}{3} * \frac{1}{4}$ [of means to multiply]

=> $\frac{5*1}{3*4}$

=> 5/12 miles

Bernie left home riding his bike at a rate of 15 mph Charlie left one hour later biking at a rate of 20 mph how long will it tak

3241004551 [841]

Answer:

Bernie left home riding his bike at a rate of 15 mph.

Charlie left one hour later biking at a rate of 20 mph.

Bernie distance = 15*t (time is represented by t)

Charlie distance = 20*(t-1) (he left after 1 hour)

15t = 20t - 20

-5t = -20

t = 4

4*15 = 60

when t = 3 hours

3*20 = 60
