<u>Answer:</u>
- The length of BC is 25 units.
<u>Step-by-step explanation:</u>
<u>We know that the triangle is an isosceles triangle. Hence, we know that AB = AC. Let's first solve for x.</u>
- => 4x + 1 = 2x + 23
- => 4x - 2x = -1 + 23
- => 2x = 22
- => <u>x = 11</u>
<u>Now, let's substitute the value into the expression.</u>
- => 3x - 8
- => 3(11) - 8
- => 33 - 8
- => <u>25</u>
<u>Hence,</u><u> the length of BC is 25 units.</u>

Answer:
Supplement of <1 = 122°
Supplement of <2 = 156°
Step-by-step explanation:
Two pairs of angles are said to be supplementary, if their measures in degrees add up to give us 180°. A supplement of am angle is simply 180° - the measure of that angle.
Given that meadure of angle 1 = 58°, the supplement of angle 1 = 180° - 58° = 122°
Also, if the measure of angle 2 = 24°, the supplement of angle 2 = 180° - 24° = 156°.
Thus:
Supplement of <1 = 122°
Supplement of <2 = 156°
Answer:
12m
Step-by-step explanation:
work out the area of the rectangle then times it by 2 because the parallelogram is twice the area of the rectangle. 8 × 4.5m = 36m². 36 ×2 = 72cm². Now you do 72 ÷ 6 = 12 . the answer is 12m.
