Answer:
e = 31
Step-by-step explanation:
The triangle on the left has 2 congruent sides , so is isosceles with 2 congruent base angles of size
= 
= 62
Then the interior angle of the triangle on the right is
180° - 62° = 118°
The triangle on the right is also isosceles with 2 congruent base angles, then
e = 
= 
= 31
Answer:
(b) 950 km
(c) 90 litres
(d) $108
Step-by-step explanation:
Henry lives 95 km from work.
Number of km from home to work = 95 km
Number of km from work to home = 95 km
One day = 95 + 95 = 190 km
<u>Assuming he works 5 days a week.</u>
1 day = 190 km
5 days = 190 x 5 = 950 km
<u>Assuming he works 5 days a week.</u>
1 day = 18 litres
5 days = 18 x 5 = 90 litres.
<u>Assuming he works 5 days a week.</u>
1 litre = 120 cents
90 litres = 120 x 90 = 10800 cents = $108
The commutative property
It states that any multiplied equation's numbers can be switched in any number and it will still have the same product.
3 * 4 = 4 * 3
