Answer:
The measure of angle G is
Step-by-step explanation:
Let
F ----> the measure of interior angle F of the triangle FGH
G ---> the measure of interior angle G of the triangle FGH
H ---> the measure of interior angle H of the triangle FGH
we know that
The sum of the interior angles in a triangle must be equal to 180 degrees
so
----> equation A
----> equation B
----> equation C
Solve the system of equations by substitution
substitute equation B and equation C in equation A
Solve for F
Find the measure of angle G
substitute the value of F
3k-1=7k+2
+1 +1
——————
3k=7k+3
-7k -7k
——————
-4k=3
/-4 /-4
Answer is K= -3/4

Step-by-step explanation:
Using factorization method;
x²+13x+40=0
x²+13+40
Find two numbers that you can add together to give the co-efficient of variable x. (I.e 13 for this question). Also, you'll find two numbers that you can multiply with each other to give you the whole number as an answer. (I.e 40 in this question). The two numbers must be the same (i.e the two numbers that will be added to give the co-efficient of x and the two numbers that will be multiplied to give the whole number must be the same two).
The two numbers are +5 and +8
The equation will therefore be = x²+5x+8x+40
You'll then factorize (I.e use a common factor of both values to bracket them)
x(x+5)+8(x+5)
(x+8)(x+5)
x is therefore (x+8=0) or (x+5=0)
x=(x=0-8) or (x=0-5)
x= -8 or x= -5
