Answer:

probability of chosing a student that has a cat and a dog is 9/25

Step-by-step explanation:

And yes the Venn diagram is wrong because you forgot to subtract 9 from 15 and 16

This makes it

[ 3 ( 6 ( 9 ) 7 ) ]

3 + 6 + 9 + 7 = 25

In triangle ABC find b to the nearest degree given a=7 b=10 and c is a right triangle
eimsori [14]

Answer:

∠B =55.00797173^{\circ}

Step-by-step explanation:

Given : a=7 b=10 and C is a right triangle

solution :

refer the attached figure .

Since ΔACB is right angled triangle so we will use trigonometric ratios .

tan\theta=\frac{perpendicular}{base}

Perpendicular = b =10

Base=a=7

Putting value in formula:

tanB=\frac{10}{7}

tanB=1.42857

B=tan^{-1}1.42857

B=55.00797173^{\circ}

Thus ∠B =55.00797173^{\circ}
