Answer:

d = 52

Step-by-step explanation:

The two angles form a straight line so they are supplementary

Supplementary angles add to 180

d+128 = 180

Subtract 128 from each side

d+128-128 = 180-128

d = 52

a+b=38

Step-by-step explanation:

Here, a represents the number of 2-points and b represent the number of 3-point basket.

As per the statement:

The basketball team scored 82 points from 2- points and 3-points baskets.

⇒ 2a+3b = 82  

It is also given that: They make 38 baskets altogether.

The diagram shows a trapezium PQRS. Find the length of side PQ, in cm​
mixas84 [53]

Answer:

30 cm.

Step-by-step explanation:

Draw a line from R perpendicular to PQ to meet PQ at T.

RQT forms a right-angled triangle  with RT = SP = 15.

So tan 36.87 = RT / TQ

tan 36.87 =  15 / TQ

TQ = 15 / tan 36.87

=  20 cm.

Now  PT = SR = 10, so

PQ = 10 + 20

= 30 cm.
