If in a triangle ac= 15 and angle abc=60 degrees what is ab?

marin [14]

Answer:

∠A=30° and AC and BC is 13 and 7.5 units respectively

Step-by-step explanation:

Given that in a right triangle ABC , right angled at C , if angle B =60 degree and AB =15 units

we have to find the remaining angles.

By angle sum property, sum of angles in right angle is 180°

∠A+∠B+∠C=180°

∠A+ 60°+90°=180

∠A=180°-150°=30°

∠A=30°

As AB= 15

Now by trigonometric ratios we find the other sides of triangle ABC

Hence, ∠A=30° and AC and BC is 13 and 7.5 unitsStep-by-step explanation:

I have to right a statistic question would this be one Out of 60 7th graders 45 or 75% of them prefer to play sports after schoo

mina [271]

Answer:

This really isn't a question. I can help you out with writing one.

John randomly selected 45% of seventh grade students in his school and asked them what their favorite time to play sports was. Of the students surveyed, 51 prefer to play sports after school. Based on this data, what is the most reasonable prediction of seventh graders in his entire grade?

Step-by-step explanation:

To answer my question, you would set up a proportion.

$\frac{9}{20} = \frac{51}{x}$ <-- the answer to that question will will be 113.

the sum of the ages of Petra and her mother is 45. her mothers is 6 years more than twice as old as Petra. how old are Petra and

otez555 [7]

Petra is 13 and her mother is 32. I used this equation:
$p + 2p + 6 = 45$
if you solve for p, you get 13. 13 times 2 plus 6 equals 32. So her mother is 32.
