Answer:

16°

Step-by-step explanation:

A ladder leans against a building . The foot of the ladder is 2 feet from the building and reaches to a point 7 feet high on the building . The measured angle formed by the ladder and building can be computed below.

The illustration forms a right angle triangle. Two sides are given and we are told to find an angle

Distance form the foot of the ladder to the building = 2 feet

The ladder reaches a point in the building which is the height of the building the ladder head started from = 7 feet

Using SOHCAHTOA principle

tan ∅ = opposite /adjacent

where

opposite = 2 ft

adjacent = 7 ft

∅ = angle formed by the ladder and the building

tan ∅ = 2/7

∅ = tan⁻¹ 2/7

∅ =  15.9453959

∅ ≈ 16°

4. In ABC, AB = 8,BC = 10, and AC = 7
Rus_ich [418]

Answer:

B, C, A

Step-by-step explanation:

If one side of a triangle is longer than a second side, then the angle opposite the first side is larger than the angle opposite the second side.

Draw the triangle.

AC (7) is opposite from B

AB (8) is opposite from C

BC (10) is opposite from A

From smallest to largest: 7>8>10

7, 8, 10

or

B, C, A

Whuch value is 23x10,000,000 written using exponents
FrozenT [24]

Answer:

2.3 \times{10}^{8}

Step-by-step explanation:

We first write powers of 23 and 10,000,000.This implies that,

23=2.3\times10

Also,

10,000,000=1.0\times{10}^{7}

We now multiply. This implies,

2.3 \times10\times1.0\times{10}^{7}

=2.3\times1.0 \times {10}^{7+1}

=2.3\times{10}^{8}

Therefore the value of 23×10,000,000

=2.3 \times{10}^{8}
