Answer:

28.8 ft

Step-by-step explanation:

We can use proportion in calculating this.

Let X= height of the shadow of 24- ft tree.

The proportion can be set up as

(15- ft tree) /( 18- ft shadow )=(24- ft tree) / X

15/18 = 24/X

Making X subject of the formula

15X = 18 × 24

X= (18×24)/15

X=28.8 ft

Hence, the shadow of the 24- ft tree is 28.8 feet

Calculate the approximate distance point A (5, 3, −2) and point B (2, −4, 8) are from the origin. Round to the nearest tenth.
bulgar [2K]
The distance of A from the origin.
√(5²+3²+(-2)²)= √(25+9+4)
                      =√38
                      =6.2

The  distance of B from the origin

√(2²+(-4)²+8²=√(4+16+64)
                     
                     =√84
                     = 9.2
