Answer:

X = 88°
(X-44°) = 44°

Step-by-step explanation:

We assume the given sum is the sum of interior angles of a triangle, so is equal to 180°.

48° +X +(X -44°) = 180°

2X +4° = 180° . . . . . . . . . . collect terms

X +2° = 90° . . . . . . . . . . . .divide by 2

X = 88° . . . . . . . . . . . . . . . subtract 2°

Then the other interior angle is ...

(X -44°) = 88° -44° = 44°

The unknown interior angles are ...

X = 88°
X-44° = 44°

First find the multiplier: 5.5% + 1 = 1.0505.

Then we do amount x (multiplier) to the power of how many years.

300 x (1.0505)^5

The answer is <span>383.79696707.

We round this to 2dp, making it £393.80

REMEMBER UNITS!!!

Hope this helps xox :)</span>
