Determine the measure of angle A

Mathematics
1 answer:
igor_vitrenko [27]3 years ago
6 0

Answer:

63*

Step-by-step explanation:

The first thing you need to do is find the value of x. What I did for this was trial and error. I tried a number, and if it was too big, I tried a smaller one. If you add up all of the angles, it should equal up to 180*, so I kept on doing this until I added up to 180.

The answer I got was x=8, so I plugged this into the equation for A and solved. 9x8 is 72, and 72-9 is 63.

Therefore, 63 is the correct answer.

A company makes two models of television.
VLD [36.1K]

Answer:

16/25

Step-by-step explanation:

length of screen B=44*(5/4)=55cm

and its width=32*(5/4)=40cm

so, screen B had dimensions 55cm by 40 cm

screen A area=44*32 cm sqr

screen B area=55*40 cm sqr

so, model A screen area/model B screen area

=(44*32)/(55*40)

=16/25

Anuta_ua [19.1K]
The heart beat rate is 70beats/minute with 80ml of blood pumped every beat. Then, the <span>volume of blood your heart pumps in one minute would be:

volume of blood per minute= volume per beat * beat per minute
</span>volume of blood per minute= 80ml/beat * 70beat/minute= 560ml/ minute<span>

</span>volume of blood per hour would be: 560ml/minute * 60 minute/hour= 33.600 ml/hour

If csc θ=8/7, which equation represents cotθ
TEA [102]
Sin θ = opposite leg/hypotenuse 
csc θ = hypotenuse /opposite leg =8/7

cot <span>θ = adjacent leg/opposite leg

hypotenuse =8
opposite leg =7
We need to find adjacent leg.

(Opposite leg)² +(adjacent leg)² = hypotenuse²
7² + </span>(adjacent leg)² =8²
(adjacent leg)² = 64 - 49
(adjacent leg)² = 15

adjacent leg=+/-√15
<span>WE need only positive root,
so </span>adjacent leg =√15

cot θ = √15/7 or 0.5533<span>
