Answer: angle A=40, Angle B=74, Angle C=66

Step-by-step explanation:

We all know that a triangle has 180 degrees.

3x-8+5x-6+4x+2=180

12x-12=180

12x=180+12

12x=192

x=16.

∠A=2(16)+8=40

∠B= 90-16=74

∠C = 5(16) -14= 66

A body of mass 50 kg explodes and splits into three pieces. The first piece has a mass of 10 kg and a velocity of [-3,2] m/s, th
fiasKO [112]

Step-by-step explanation:

From the conversation of angular momentum

Initial momentum=final momentum

Here,

Since body is initially resting, it's momentum must be zero.

Let v be velocity of third piece. Then

0= 10(-3i+2j) + 18(5i-4j) + 22v

Solving this we get,

v= 4/22(15i+13j).

Nikki had 70% of her savings left in her bank account. If she has $230 in her bank account, how much did she start with?
Alex

Answer:

$299

Step-by-step explanation:

Given that 70% is $230 you can divide this by 7 to get 10%.

10% is 23. The remaining percentage we need is 30.

Soo 10% x 3 = 30%. (23x3)

23 x 3 = 69.

69 + 230 = $299

2) -7x + 5y=10<br> 4x - 5y=-10
bezimeni [28]
To solve this, the problem is solvable by elimination. So you see how the 5y and -5y cancel out? You basically add those two and you add the -7x and 4x and 10 and -10 leaving you with -3x=0. Dividing by each side gives you x=0. Then, plug 0 in for x in -7x+5y=10. Giving you

-7(0)+5y=10.

0+5y=10

5y=10
Divide by 5 on each side giving you y=2. So your answer is (0,2).
