Find the m∠RQP of the triangle

dmitriy555 [2]

Step-by-step explanation:

in the given figure ,

the two sides of the triangle are equal , so their opposite angles are equal .

so , we get

=》Angle RPQ = Angle PRQ = 65°

and some of interior angels of the triangle measures 180°

so,

=》RPQ + PRQ + RQP = 180°

=》65° + 65° + RQP = 180°

(Because RPQ = PRQ = 65°)

=》130° + RQP = 180°

=》RQP = 50°

You usually buy a 16.5-ounce bottle of shampoo. There is a new bottle that says it gives you 30% more free.

Katarina [22]

Answer:

$\frac{x-16.5}{16.5}=0.30$

Hopefully, this is your desired setup. (I noticed the formula you have to fill in there.)

Have a good day.

Step-by-step explanation:

Hi.

You could use the percent change formula.

Since we know it is a percent increase then we will do new-old instead of old-new:

$\frac{\text{new}-\text{old}}{\old}$

x is the new amount of shampoo.

16.5 is the original amount (old) of shampoo.

The percent increase is 30%=0.30 .

So we have the following equation:

$\frac{x-16.5}{16.5}=0.30$

We could have found the equation like this:

$16.5+16.5(0.30)=x$

Subtract 16.5 on both sides:

$16.5(0.30)=x-16.5$

Divide both sides by 16.5:

$0.30=\frac{x-16.5}{16.5}$

By us of symmetric property of equality:

$\frac{x-16.5}{16.5}=0.30$

If c=25 and B=75 degrees, find a. Round to the nearest tenth.

worty [1.4K]

Answer:

a=6.9

Step-by-step explanation:

Since you know that C is a right angle, you can use the Law of Sines to find a. The first step is to find the size of the angle A, which is 180-74-90=16. Now, you set up a ratio that involves 3 knowns and one unknown to get $\frac{\sin(90^\circ)}{25} = \frac{\sin(16^\circ)}{a}$ , which after cross multiplying yields $a=\sin(16^\circ)\cdot25\approx 6.9$ . PM me if you have any questions?
