Answer:
The answer is C:$87.50
Step-by-step explanation:
Ben - 1$
David - 0.75$
For each Bagel, Ben paid 0.25$ extra.
Then the total bagel Ben bought = 12.5/0.25 = 50 and the money spent = 50$
Then david spent = 3/4*50 = 37.5$
Total = 50+37.5 =$87.50
Answer:
Pt A:I would say net A because if you fold net b it's going to be very tricky and hard to make and if you fold net A you get the exact shape.
Pt B:AB is 3in BC is 4 in and CD is 5 in.
Step-by-step explanation:
i hope this helps this helps you get out of trouble
From the picture, we see that there are two congruent sides. Therefore, following the Isosceles Triangle Theorem, if two sides in a triangle are congruent, then the angles opposite those sides are congruent. So, we know that the angles opposite of the congruent sides have an angle measure of x°. We are given the measure of the angle at the top vertex of 100°. Following the Triangle Sum Theorem, the three interior angles in a triangle must sum up to 180°. Therefore, we can create an Algebraic equation to solve for the two base angles that measure x°.
x+100+x=180
x=the base angle measures since they are congruent.
100+x+x=180
Community Property of Addition
100+2x=180.
Added x+x as like terms to = 2x.
100-100+2x=180-100
Subtraction of 100 from both sides to cancel it out and move it.
2x=80
Subtraction operation
2x/2=80/2
Divided by 2 to cancel it out on both sides and move it.
x=40°.
Therefore, the two base angles (angles opposite of the two congruent sides) are 40°.
2(40)+100=80+100=180.
So x=40
You can find the value of x using the trigonometric function of cosine.
cos x = adj/hyp
cos 49 = x/55
55(cos 49) = x
36.083 = x
