I don’t know how to solve for Q.
Naya [18.7K]

Answer:

  ∠Q = 75°

Step-by-step explanation:

Start by recognizing that the triangle is isosceles (the long sides are marked as being equal-length). That means angles Q and R have the same measure.

Next, you use the fact that the sum of angles is 180° to write an equation.

  ∠R +∠P +∠Q = 180°

  (2x +15)° +x° +(2x +15)° = 180° . . . . substitute the known values

  5x +30 = 180 . . . . . . . . . . . . . . . . divide by °, collect terms

  5x = 150 . . . . . . . . subtract 30

  x = 30 . . . . . . . divide by 5

Then angle Q is ...

  ∠Q = (2x +15)° = (2×30 +15)°

  ∠Q = 75°

HELP PLEASE!!
shutvik [7]

Answer:

6.5 x 10^6 To answer this question, you need to divide the mass of the sun by the mass of mercury. So 2.13525 x 10^30 / 3.285 x 10^23 = ? To do the division, divide the mantissas in the normal fashion 2.13525 / 3.285 = 0.65 And subtract the exponents. 30 - 23 = 7 So you get 0.65 x 10^7 Unless the mantissa is zero, the mantissa must be greater than or equal to 0 and less than 10. So multiply the mantissa by 10 and then subtract 1 from the exponent, giving 6.5 x 10^6 So the sun is 6.5 x 10^6 times as massive as mercury.

What is the approximate value of q in the equation below?
gayaneshka [121]

<u>Given</u>:

The given equation is q+\log _{2}(6)=2 q+2

We need to determine the approximate value of q.

<u>Value of q:</u>

To determine the value of q, let us solve the equation for q.

Hence, Subtracting \log _{2}(6) on both sides of the equation, we get;

q=2 q+2-\log _{2}(6)

Subtracting both sides of the equation by 2q, we have;

-q=2-\log _{2}(6)

Dividing both sides of the equation by -1, we have;

q=\log _{2}(6)-2

Now, substituting the value of log_2(6)=2.585, we have;

q=2.585-2

Subtracting the values, we get;

q=0.585

Thus, the approximate value of q is 0.585

Hence, Option C is the correct answer.
