Sorry if i get it wrong hope it helps
Use Pythagorean theorem
a^2 + b^2 = c^2
In other words, sum of the squared smaller lengths are equal to the squared of the longest length
15^2 + 17^2 = c^2
225 + 289 = c^2
c^2 = 514
c = square root of 514
= 22.67156
Round it
Solution: 22.7 km
Answer:
£2380.13
Step-by-step explanation:
An increase of 8.5% is 100% + 8.5% = 108.5% = 1.085 , then
£2193.67 × 1.085 = £2380.13 ( to 2 dec. places )
Answer:
x = 11, y = 22
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan60° =
, then
tan60° =
=
=
( multiply both sides by x )
11
= x ×
( divide both sides by
)
11 = x
Using Pythagoras' identity in the right triangle
y² = x² + (11
)² = 11² + 363 = 121 + 363 = 484 ( square root of both sides )
y =
= 22
