Answer:

The sum of the interior angles of any triangle are equal to 180

therefore in this triangle, m<a+m<c+m<b=180

we know that 9x-26 and m<a are supplementary angles (meaning they add to 180) and therefore,

9x-26+a=180

9x+a=206

a=206-9x

(206-9x)+(2x-12)+(4x+43)=180

combine like terms

-3x+237=180

-3x=-57

x=19

if x=19 then we can substitue it in for c

4x+43=c

4(19)+43=c

c=119

Answer: a and d

Step-by-step explanation:

(to find all points of discontinuity, set denominator equal to zero and solve)

$x^2-7x+10=0\\\\$

(to factor, find two numbers when added together equal -7 and when multiplied together equal 10)

-2 + -5 = -7

-2(-5) = 10

-2 and -5 are the two numbers

$(x-2)(x-5)=0\\\\x-2=0\\x=2\\\\x-5=0\\x=5\\\\x=2,5$
