(WILL GIVE BRAINLIEST)
weeeeeb [17]

Answer:

m<I=57

m<J=57

m<K=66

Step-by-step explanation:

All the angles in a triangle add up to 180 degrees.

m<I= 3x+18

m<K= 5x+1

m<I is congruent to m<J.

We can plug the information we already know into the equation.

3x+18+3x+18+5x+1=180

11x+37=180

Subtract 37 from both sides.

11x=143

x=13

Now, we can find out what the angles are.

m<I= 3x+18

m<I=3(13)+18

m<I=39+18

m<I=57

We know that m<I=m<J, so they are both equal to 57 degrees.

m<J=57

Now for m<K:

m<K=5x+1

m<K=5(13)+1

m<K=65+1

m<K=66

We know this is correct because 57+57+66=180.

1 over 3b = 4 over 5 . Which of the following equals b in this equation? (4 points)
vfiekz [6]

Answer:

none of the answers listed are equivalent to b (22/5, 11/8, 2/5, 1/4)

Step-by-step explanation:

\frac{1}{3b} = \frac{4}{5}

to simplify, cross multiply

(1 · 5  =  3b · 4)

(5 = 12b)

divide both sides by 12 to isolate b,

\frac{5}{12} =\frac{12b}{12}

\frac{5}{12} = b

None of the answers listed are equivalent to 5/12

\frac{5}{12} \neq\frac{22}{5}

\frac{5}{12} \neq\frac{11}{8}

\frac{5}{12} \neq\frac{2}{5}

\frac{5}{12} \neq\frac{1}{4}
