If lines a and b are parallel, and m<8=150, what is the m<2

ss7ja [257]

Step-by-step explanation:

$\underline{\large{ \tt{G \: I \: V \: E \: N}}} :$

Line a & b are parallel
m ∠ 8 = 150 °

$\underline{ \large{ \tt{T \: O\: \: F \: I \: N \:D}}} :$

m ∠ 2

$\underline{ \large{ \tt{S\: O \:L \: U \: T \: I \: O \: N}}} :$

$\large{ \tt{m \: \angle \: 8 \: + \: m \: \angle \: 2 = 180 \degree}}$ [ Sum of co-interior angles ]

⤑ $\large{ \tt{150 \degree \: + m \: \angle \: 2}} = 180 \degree$

⤑ $\large{ \tt{m \angle \: 2 \: = \: 180 \degree - 150 \degree}}$

⤑ $\large{ \tt{m \: \angle \: 2 \: = \bold{ \tt{30 \degree}}}}$

$\red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \bold{ \tt{30 \degree}}}}}}}}$

Hope I helped ! ♡

Have a wonderful day / night ! ツ

Assume that all interest is simple interestBerger Car rental borrow $8500 at 4% interest to cover the increase cost of the auto

viva [34]

we know that

The formula of simple interest is equal to

$I=P(rt)$

In this problem

we have

I=$170

P=$8,500

r=4%=4/100=0.04

t=?

substitute given values in the formula

$\begin{gathered} 170=8,500(0.04t) \\ Solve\text{ for t} \\ t=\frac{170}{8,500*0.04} \\ t=0.5\text{ years} \end{gathered}$

therefore

0.5 years=6 months

<h2>The answer is 6 months</h2>
