Answer:
x = 5
Step-by-step explanation:
Using the tangent ratio and the exact value
tan60° = , then
tan60° = = = ( multiply both sides by 5 to clear the fraction )
x = 5
Answer:
6082.70
Step-by-step explanation
15300 × .8575 × 8575 × .8575 × .8575 × .8575 × .8575 = 6082.69727735
6082.69727735 rounds to 6082.70
Answer:
x=12
Step-by-step explanation:
QS=QR+RS
2x-11=7+x-6
x=12
(a)
The ratios of corresponding sides are equal
= 2 ← scale factor
hence w = 2 × 2.3 = 4.6 cm
(b)
The perimeters are linear and will also be proportional with a scale factor of 2
the areas are proportional with scale factor 2² = 4
That is the area of rectangle B is 4 times the area of rectangle A
In general
If 2 figures are similar then linear ratio of sides = k
Then the ratio of their areas is k²
and the ratio of their volumes is k³
