Please explain how this digraph works.
dusya [7]

Angles XQL and MQR are congruent because they are vertical angles. So

209 - 13 <em>b</em> = 146 - 4 <em>b</em>

Solve for <em>b</em> :

209 - 13 <em>b</em> = 146 - 4 <em>b</em>

209 - 146 = 13 <em>b</em> - 4<em> b</em>

63 = 9 <em>b</em>

<em>b</em> = 63/9 = 7

Then the measure of angle XQL is

(209 - 13*7)º = 118º

Help please, i dont understand

Answer:

formula: y-y1 = m(x-x1)

Step-by-step explanation:

General:

1. find 2 points directly on the line and apply the formula y2-y1 over x2-x1 this answer equals m

2. then add it into the formula y-y1 = m(x-x1) remember x and y are variables so only put numbers in y1 and x1

3. solve the problem

Example:

line 1:

1. y2-y1 over x2-x1 is 4-6 over 6-4 = -1

2.  y-6 = -1(x-(-4) or y-6 = -1(x+4)

3. y-6 = -1x-4

4. y = -1x-2

3. the gradient equals: y = -1x-2

Hope this helps :) Let me know if you need a better example

A triangle has sides of length 2, 2, and 3. Which of the following is the measure of the obtuse angle of the triangle?
kramer

Answer:

97.18^{\circ}

Step-by-step explanation:

An obtuse angle in the triangle is opposite to the greatest side. The greatest side in the triangle with sides lengths 2, 2 and 3 is side with length 3. By the cosine rule,

3^2=2^2+2^2-2\cdot 2\cdot 2\cdot \cos \alpha,\\ \\9=4+4-8\cos \alpha,\\ \\-8\cos \alpha=9-4-4=1,\\ \\\cos \alpha=-\dfrac{1}{8},\\ \\\alpha\approx 97.18^{\circ}.
