STVU is an isosceles trapezoid. If SV = 3x - 11 and TU = x + 13, find the value of x

1 answer:

7 0

The given trapezoid will have the sides ST, TV, VU, and US. Each of these can be assigned as base or legs. By this, it can be deduced that the given sides, SV and TU are the diagonals. Because the trapezoid is isosceles, the values of SV and TU should also be equal.

SV = TU
3x - 11 = x + 13

Transpose the terms with x and the constants in each sides of the equation.

3x - x = 13 + 11
2x = 24
<em> x = 12</em>

Thus, the value of x from the equation is 12.

If sinX= 0.9, what is the value of cos X?<br><br> Round the value to the nearest thousandth.

SSSSS [86.1K]

Answer: sqrt(19)/10

Step-by-step explanation:

sinx=0.9

x=arcsin(0.9)

Insert x for cos(x):

cos(arcsin(0.9)=

Use identify $cos(arcsin(x))=\sqrt{1-x^{2} }$ , so

$\sqrt{1-(\frac{9}{10})^{2}} =\sqrt{\frac{19}{100} } =\frac{\sqrt{19}}{10}$

Sorry if this is confusing.

Please help me with my homework I don't understand it

Damm [24]

Answer:

Part A:

0.1111111111111 = 1/9

Part B:

Step-by-step explanation:

Part A:

When I put 0.111111111 into my calculator I get a conversion of 1/9.

Part B:

The fraction 1/9 means that for every 9 kids he surveyed, 1 of them replied "yes."

So covert 1/9 into x/27

27/9 = 3 which means 9 goes into 27, 3 times.

Multiply 1 by 3.

1 x 3 = 3

Put into fraction form

3/27

This means 3 students out of 27 answered "yes."
