Answer:

A: 65° B: 65° C: 125° D: 125°

Step-by-step explanation:

It is an equilateral(shown by the two dashes) and all angles in a triangle add up to 180°.

180-50 divided by 2 to give you A and B angles.

Then angled on a straight line add up to 180° so if you take angle A away from 180° you will get the answer to angle C.

The same for angle D.

If AB=2(x+1) BC=3x+1 and AC=4(x+2) then find the value for x,AB,BC and AC

taurus [48]

Givens

AB + BC = AC

AB = 2(x + 1)

BC = 3x + 1

AC = 4(x + 2)

Substitute and Solve

AB + BC = AC

2(x + 1) + 3x + 1 = 4(x + 2) Remove the brackets on the left

2x + 2 + 3x + 1 = 4(x + 2) Collect the like terms on the left

5x + 3 = 4(x + 2) Remove the brackets on the right.

5x + 3 = 4x + 8 Subtract 4x from both sides.

5x - 4x + 3 = 8

x + 3 = 8 Subtract 3 from both sides

x =8 - 3

x = 5

AB=2(5 + 1) = 2 * 6 = 12

BC = 3x + 1 = 3*5 + 1 = 15 + 1 = 16

AC = 4(5 + 2) = 4*7 = 28

Please help me use full explanation please hurry

Keith_Richards [23]

Step-by-step explanation:

As we can see the question given

f(x) is varying accordingly to the interval

f(x) = 2 if 2<x≤4

The value of function is 2 for the interval 2 to 4

and interval is open at x=2 and closed at x = 4

f(x) = x + 3 if 4<x<8

The value of function is x + 3 and it is open at x = 4 and x = 8

f(x) = 2x if x $\geq$ 8

The value of function is 2x for x greater than or equal to 8
