Mathematics
1 answer:
Pepsi [2]3 years ago
8 0

Answer:

x = 4

Step-by-step explanation:

the given figure is of an isoceles triangle.

The two angles opposite are congruent(i.e78 degrees) .

That is the sides opposite to them are also congruent.

I. e 4x + 23 = 10x - 1

I. e 4x - 10x = -1 -23

I. e -6x = -24

I. e -x. = -24/6

Dividing by 6 to 24 we get,

-x = -4

therefore by removing the minus sign from both the sides,

the answer comes x = 4

Hello I need help on the 4 questions please help thank you:D​
boyakko [2]

Step-by-step explanation:

1. simple interest

I= p × r × t

I = 1050 × 4.5 × 2

I = $9450

2. principal

p = I/(rt)

p= 22.50/ (3× 3)

p = 22.50/9

p = $2.5

3. simple interest

I= p × r × t

I = 500 × 5 × 3

I = $7500

4. time

first convert r to decimal

r= r/100, r= 3.5 / 100

r= 0.035

t = i/(pr)

t = 43.75/ (2500× 0.035)

t = 43.75/ 87.5

t = 0.5 year or 6 months

These angles should add to 180 degrees because the angles are on a straight line so you should use the formula x=180-90-38. Therefore, x should be 52 degrees
