klasskru [66]

Answer:

there is 16.08 foot high does the ladder reach on the building

Step-by-step explanation:

The computation of the high does the ladder reach on the building is shown below:

Given that

length of the ladder = 17 ft

angle -between the ground and the ladder = 75 degrees

Based on the above information

Here we used the trig-ratio to calculate the same

Sin \theta  = \frac{oppo}{hyp} \\\\Sin 71^{\circ} = \frac{h}{17}

0.946 × 17 = h

The height is 16.08 foot

Hence, there is 16.08 foot high does the ladder reach on the building

Answer:

Population in 2050 = 11,369,600,000

Step-by-step explanation:

Given:

Population in 2000 = 6,080,000,000

Rate of increase = 1.26%

Find:

Population in 2050

Computation:

Number of year = 50

Population in 2050 = Population in 2000[1+r]ⁿ

Population in 2050 = 6,080,000,000[1+1.26%]⁵⁰

Population in 2050 = 6,080,000,000[1.87]

Population in 2050 = 11,369,600,000

sine x = 0.8947

sine-1 of 0.8947 = 63.4699

x = 63.4699
