the picture in the attached figure
we know that
m∠1+m∠2+m∠3+m∠4=180°
m∠jkm=m∠1+m∠2+m∠3
so
m∠jkm+∠4=180°
m∠jkm=5x+18
∠4=x
substitute
(5x+18)+x=180°------> 6x=180-18------> x=162/6--------> x=27°
therefore
the answer is
the measure of angle 4 is equal to 27 degrees
Answer:
A (59)
Step-by-step explanation:
A triangle is from what I've learned, always equal to 180° degrees. So 28 plus 93 is 121, and 121 plus 59 is 180.
Answer:
See explanation
Step-by-step explanation:
Assuming the given equation is
To solve for r, we first divide both sides by a.
We now subtract 5 from both sides:
We now divide through by - 1 to get:
Or
Answer:
c
Step-by-step explanation:
15 Δ 25
20
15 + 20 = 35 (I did this because the two <u><em>smallest</em></u> numbers added together need to be grater than the side with the biggest number.)
35 <u>></u> 25

Answer:
4 and 9
Step-by-step explanation:
t2-13t+36=0
factors of 36 are:
1,2,3,4,6,9,12,18,36
factors that add up to 13 are: 9*4
factorise the equation:
(t-9)(t-4)=0
t-9=0 ---> t=9
t-4=0 ---> t=4
