Answer:

Step-by-step explanation:

D. 123°

The sum of the entire interior of the triangle is 180°

A straight line is 180° as well.

Let's say that the unlabeled angle is x.

63° + 60° = 123°

180° - 123° = 57°

x = 57°

x + ∠1 = 180°

57° + ∠1 = 180°

180° - 57° = 123°

D. 123°

Factor the polynomial

WARRIOR [948]

3x⁶y² + 57x⁵y³ + 252x⁴y⁴
= 3x⁴y²(x² + 19xy + 84y²)
= 3x⁴y²(x² + 12xy + 7xy + 84y²)
= 3x⁴y²(x(x + 12y) + 7y(x + 12y))
= 3x⁴y²(x + 12y)(x + 7y)

A building 78 ft high casts a 195-ft shadow. Sarah casts a 10-ft shadow. The triangle formed by the building and its shadow is s

mylen [45]

This can be solved by similar triangles, which means you can cross multiply and divide. 78/195=x/10. 78(10)=780 and divide 780 by 195, you'll get the answer is 4. This means Sarah is 4 ft tall.

$8000 principal earning 5% compounded annually, after 6 years

Verdich [7]

Future amount after 6 years will be: $10720.76

Step-by-step explanation:

Principal = $8000

Interest= 5% compounded annually

Time = 6 years

We need to find A (future amount)

The formula used is:

$A=P(1+\frac{r}{n})^{nt}$

A= Future amount

P= Principal amount

r= interest rate

n= no of times interest is applied

t= time

Putting values and finding A

P=8000. r=0.05, n=1, t=6

$A=P(1+\frac{r}{n})^{nt}\\A=8000(1+\frac{0.05}{1})^{1*6}\\ A=8000(1+0.05)^{6}\\ A=8000(1.05)^{6}\\A=10720.76$

So, Future amount after 6 years will be: $10720.76
