Tyrel And Diego are playing basketball. Together they scored 45 points.Tyrel scored two times as many points as Diego. How many
pshichka [43]

Answer:

Tyrel scored 30 and Diego scored 15

Step-by-step explanation:

This is because the ratio of the score is 2:1  (Tyrel : Diego)

and if you add that together you get 3

which means you have to divide 45 by 3 which gives you 15

and this means I part = 15

so with the ratio 2:1 you have to multiply 15 by each ratio

so 15 x 2 = 30 and 15 x 1 = 15

which gives you 30 and 15

Find angle ADB of the equation
Aloiza [94]

Answer:

m\angle ADB = 59\°.

Step-by-step explanation:

Given:

\angle BDC = 31\°

We need to find \angle ADB.

Solution:

Now we can see that given figure is a rectangle with diagonals drawn in it.

So by properties of rectangle which states that;

"All angles of a rectangle are 90°."

So we can say that;

\angle A = \angle B = \angle C = \angle D = 90\°

But

\angle D = \angle BDC + \angle ADB

Substituting the values we get;

31\°+\angle ADB = 90\°

Subtracting both side by  by 31 we get;

31\°+\angle ADB -31\°= 90\°-31\°\\\\m\angle ADB = 59\°

Hence m\angle ADB = 59\°.
