Answer:
integer
Step-by-step explanation:
Take 145-115 because for this your supposed to add all numbers inside to get exterior angle so you would do 145-115=30
R would be 30
R=30
Hope this helps
Answer:
<em> 4.5m</em>
Step-by-step explanation:
The set up is a right angles triangle
Height of the shed = opposite side = 6cm
Distance of the ladder from the shed = adjacent = 4.5m
Lenght of the ladder = Hypotenuse = x
Using pythegoras theorem to find the length of the ladder
hyp² = opp²+adj²
hyp² = 0.06² + 4.5²
hyp²= 0.0036+20.25
hyp² = 20.2536
hyp = √20.2536
hyp = 4.50m
<em>Hence the length of the ladder is 4.5m</em>
