Go through the list of choices. Add up the angles. If the result is 180, then we have the answer

A) 60+45+70 = 175, which isn't 180 so we scratch this off the list

B) 30+85+25 = 140, also doesn't work

C) 55+90+35 = 180, we found the answer

D) 110+15+45 = 170, doesn't work

------------------------

In summary, the answer is choice C) 55 degrees, 90 degrees, 35 degrees

Answer:

x equals 3.00cm

Step-by-step explanation:

Use Pythagoras' Theorem.

a = (14x-45)

b = (16x+27)

c = (25x)

Plug in the variables above into Pythagoras' Theorem that is, a^2+b^2=c^2.

Solve the resulting quadratic equation and reject the negative answer as length is always positive.

Marian went shopping and bought clothes for $66.17 and books for $44.98. She then had a meal at the mall for $20.15. Which is th

scZoUnD [109]

Answer:

Either 130 or 131 would be acceptable.

Step-by-step explanation:

When we estimate, we do not use exact values.

66.17 is close to 66

44.98 is close to 45

20.15 is close to 20

Add the estimates together: 66+ 45+ 20 = 131

We could also estimate 66.17 to 65 which would give us an estimate of 130

ki77a [65]

Answer:

Fundamental theorem of algebra, rational root theorem, Descartes rule of signs, remainder theorem, and the factor theorem can be utilized in solving polynomials and their depressed equations.

Polynomial functions can be written when given the zeros by determining the factors of the function, and multiplying the factors.

SOLVE FOR M. please :)

Answer:

$m = - 28$

Step-by-step explanation:

$\frac{ - 3}{7} m = 12$

$\frac{ - 7}{3} ( \frac{ - 3}{7})m = \frac{ - 7}{3} \times 12$

$\frac{ - 1}{3} ( - 3)m = \frac{ - 7}{3} \times 12$

$- 1( - 1)m = \frac{ - 7}{3} \times 12$

$1 \times m = \frac{ - 7}{3} \times 12$

$m = \frac{ - 7}{3} \times 12$

$m = \frac{ - 7}{3} (3 \times 4)$

$m = - 28$
