What is this please help I need this completed
Arturiano [62]

Answer:

angles 3 and 4 both equal a 90 degree angle or bisect a 90 degree angle.

angle 5 is 44-degrees because it is complementary or vertical to the 44 degree angle.

x=32 because it is on the same line as the 44-degree angle and a line is 180 so 180-44=136 and to get the rest of x you would do the equation backwards so 136 divided by 4 is 34 and 36-2=32

angle a is 136 described above.

angle b, because it is on the same line as the 46 degree angle is 180-46=134

now im pooped :(

Calculate the compound interest on an investment of R6500 at 7,5% per annum invested for 3 years​
Lemur [1.5K]

Answer:

Compound interest = Rs 1,575 (Approx.)

Step-by-step explanation:

Given:

Amount invested = R.s 6,500

Rate of interest = 7.5% per annum

Number of year = 3 year

Find:

Amount of compound interest

Computation:

Compound interest = P[(1+r)ⁿ - 1]

Compound interest = 6500[(1+7.5%)³ - 1]

Compound interest = 6500[(1+0.075)³ - 1]

Compound interest = 6500[(1.075)³ - 1]

Compound interest = 6500[1.2423 - 1]

Compound interest = 6500[0.2423]

Compound interest = 1574.95

Compound interest = Rs 1,575 (Approx.)
