skelet666 [1.2K]

Answer:

15.10 ft

Step-by-step explanation:

It would be helpful to draw the figure from the problem statement above. Drawing it, would give you a right triangle shape where the base is equal to 10 ft + 8 ft = 18 ft with the angle of 40 degrees. We use knowledge on trigonometric functions to solve this.

tan (theta) = opposite side / adjacent side

tan 40 = x / 18

x = 15.10 ft

IS IT (A , B ) CAN SOMEONE HELP PLEASE !!!!!!!!!!!!!!!!!
andriy [413]

Answer: 1% is your answer

It's (1/100) * 100 or 1% is the percentage strength of a 1:100 solution.

Step-by-step explanation:

l NOTE:

l To change ratio strength to percent strength, it is

sometimes convenient to "convert" the last two zeros in

a ratio strength to a percent sign (%),

l change the remaining ratio to a common fraction, and

then to a decimal fraction in expressing percent.

l Examples:

l 1:100 =1/1% = 1%

l 1:200 = ½% = 0.5%

l 3:500 = 3/5% = 0.6%

l 1:2500 = l/25% = 0.04%

l 1:10,000 = 1/100% = 0.01%

Complete the table by supplying the measure of inscribed angle and its intercepted arc​
Nadusha1986 [10]

Answer/Step-by-step explanation:

Based on the inscribed angle theorem, any inscribed angle = ½ of its intercepted arc

Thus:

✔️Inscribed angle = 57°

Intercepted arc would be: 2*57 = 114°

✔️Intercepted arc would be: 123°

Inscribed angle = ½(123) = 61.5°

✔️Intercepted arc would be: 46°

Inscribed angle = ½(46) = 23°

✔️Inscribed angle = 69°

Intercepted arc would be: 2*69 = 138°

✔️Intercepted arc would be: 155°

Inscribed angle = ½(155) = 77.5°
