Answer: choice B, 40.5 degrees

The triangle is isosceles based on the fact that AC = BC (the tick marks are the same). The angles opposite the congruent sides are also congruent

angle A = angle B = x for some unknown number x

The three angles A,B,C add to 180, so,

A+B+C = 180

x+x+99 = 180

2x+99 = 180

2x = 180-99

2x = 81

x = 81/2

x = 40.5

So angle A and angle B are both 40.5 degrees

Check:

A+B+C = 180

40.5+40.5+99 = 180

180 = 180 answer is confirmed

==============================

Edit

The sides with the two tick marks are the same length, so 7x-4 is the same as length as 31

7x-4 = 31

7x = 31+4

7x = 35

x = 35/7

x = 5

Answer is choice B) 5

kiran and clare live 24 mile away from each other along a rail trail. One Saturday the two friends started walking toward each o
scZoUnD [109]

Answer:

11:45\ am

Step-by-step explanation:

Total distance between Kiran and Clare is 24 miles. They started walking at 8.00 am.

Speed of Kiran is 3 miles/hr and speed of Clare is 3.4 miles/hr.

So the relative speed of them is,

=3+3.4=6.4 miles/hr

Both the speed are added as they moving in opposite direction.

We know that,

\text{Relative speed}=\dfrac{\text{Relative distance}}{\text{Time}}

i.e \text{Time}=\dfrac{\text{Relative distance}}{\text{Relative speed}}

Putting the values,

t=\dfrac{24}{6.4}=3.75\ hr=3\ hr\ 45\ min

As they started at 8.00 am, so the time at which will meet will be,

=8+3\ hr\ 45\ min=11:45
