0.25q + 0.1d = 4.95
d = 3q

0.25q + 0.1(3q) = 4.95
    0.25q + 0.3q = 4.95
               <u>0.55q</u> = <u>4.95</u>
                0.55     0.55
                      q = 9
0.25(9) + 0.1d = 4.95
    2.25 + 0.1d = 4.95
  <u>- 2.25             - 2.25</u>
               <u>0.1d</u> = <u>2.7</u>
                0.1     0.1
                    d = 27

How many distinct triangles can be formed for which m∠E = 64°, g = 9, and e = 10?<br> triangle(s)
Shalnov [3]

Using the law of sines, it is found that 1 triangle can be formed with the given conditions.

<h3>What is the law of sines?</h3>

Suppose we have a triangle in which:

  • The length of the side opposite to angle A is a.
  • The length of the side opposite to angle B is b.
  • The length of the side opposite to angle C is c.

The lengths and the sine of the angles are related as follows:

\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}

Hence, for this problem, we have that the relation is:

\frac{\sin{64^\circ}}{10} = \frac{\sin{G}}{9}

\sin{G} = 0.9\sin{64^\circ}

\sin{G} = 0.8089

G = \arcsin{0.8089}

G = 54º

A triangle can have one angle of 64º and another of 54º, hence 1 triangle can be formed with the given conditions.

How do I do this because I need help ?
OverLord2011 [107]

Answer:

I believe the second one

Step-by-step explanation:

Because it's angles are all less than 90 degrees so it could be an acute triangle. I am sorry if it is wrong.

Chords and intersect in circle O as shown in the diagram. Two of the angle measurements are marked. What is mCED?
jenyasd209 [6]

we know that

The measure of the interior angle is the half sum of the arcs comprising it and its opposite

so

m∠CED=\frac{1}{2} *(arc\ AB+arc\ CD)

see the attached figure with letters to better understand the problem

arc\ AB=82° ------> by central angle

arc\ CD=48° ------> by central angle

Substitute the values in the formula above

m∠CED=\frac{1}{2} *(82+48)

m∠CED=\frac{1}{2} *130

m∠CED=65°

therefore

<u>the answer is</u>

m∠CED=65°
