We will use angle sum property of triangle here
sum of three angles of triangle =180
35.5+82.6 + third angle =180
118.1 + third angle =180
third angle =180-118.1 = 61.9
third angle =61.9 degrees (option C)
You meant to say x^2 - 49 and the second binomial is x^2 - 16.
x^2 - 49 = (x - 7) (x + 7).
Set each factor to 0 and solve for x individually.
x - 7 = 0
x = 7
x + 7 = 0
x = -7
Do the same for x^2 - 16.
Here is the set up:
x^2 - 16 = (x - 4) (x + 4).
Take it from here.
Answer:
8x+8y
Step-by-step explanation:
y + 3x + 4y + 2x + 3y +3x
<em>With</em><em> </em><em>this</em><em> </em><em>we</em><em> </em><em>group</em><em> </em><em>x</em><em> </em><em>with</em><em> </em><em>x</em><em> </em><em>and</em><em> </em><em>y</em><em> </em><em>with</em><em> </em><em>y</em><em> </em><em>and </em><em>in</em><em> </em><em>ascending</em><em> </em><em>order</em><em> </em><em>so</em><em> </em><em>x</em><em> </em><em>comes</em><em> </em><em>before</em><em> </em><em>y</em>
3x+2x+3x
And the y with y
y+4y+3y
Which is;
3x+2x+3x+y+4y+3y
8x+8y
To convert a faction to a decimal you have to divide the denominator into the numerator.
1 ÷ 2 = 0.50
