Could someone help me
Arturiano [62]
The answer is D. 44 degrees.


It’s not A because that would mean the angle is over 90 and it’s not because you can see that it’s smaller than a right angle.


It’s not B because that would mean it’s a bit smaller than a right angle but it’s a lot smaller.


It’s not C because that wound mean the angle is about a 90 degrees right angle but it’s not.


D is the most reasonable answer.

Hope this helps! :)

An athletics club has junior
Brums [2.3K]

Answer:

The total number of members are 128 members

Step-by-step explanation:

From the question, mixing the ratio of children to adult, we have ;

7:9

There are 16 more adult members

So if there are x children, then there are 16 + x adults

Thus, the total number of members will be;

16 + x + x = 2x + 16

Now, we have that;

7/16 * (2x + 16) = x

7(2x + 16) = 16x

14x + 112 = 16x

16x-14x = 112

2x = 112

x = 112/2

x = 56

The total number of members is thus;

2(56) + 16 = 128
