Answer:

a = 49°

Explanation:

You use the rule ‘exterior angle of a triangle’ which states that the exterior angle is equal to the sum of the two opposite interior angles.

To put it mathematically:

a + a = a + 49° (Ext angles of triangle)
a = a - a + 49°
a = 49°

Alonzo loaned jeremy $325.18 for 1 year at a simple interest rate of 12 5/8%. how much interest will jeremy have to pay?
gayaneshka [121]

Jeremy will pay $41.05 interest.

We know that, Interest = PRT/100

where,

P = principal

R = rate

T = time

For given question, principal (P) = $325.18

interest rate R = 12 5/8%

                        = 12.625%

And period T = 1 year

We need to find the interest.

⇒ Interest = PRT/100

⇒ Interest = (325.18 × 12.625 × 1) / 100

⇒ Interest = 4105.3975 / 100

⇒ Interest = $41.05

Therefore, Jeremy will pay $41.05 interest.

Find the value of x so that line m is parallel to line l.
RideAnS [48]

Answer:

-17

Step-by-step explanation:

The angles are corresponding angles so when the lines are parallel, the lines are equal

3x-12 = 4x+5

Subtract 3x from each side

3x-12 -3x = 4x+5-3x

-12 = x+5

Subtract 5 from each side

-12 -5 = x+5-5

-17 = x

Step-by-step explanation:

The angles in a triangle always add up to 180°

∴ 33 + 112 + a = 180

∴a=35°
