In ΔRST, ∠R = 85° and ∠S = 52°. Find ∠T.
fenix001 [56]

Answer:

43°

Step-by-step explanation:

A triangle has a total angle of 180° and we can use it to find the answer.

The attachment is a visualization of the triangle.

In order to find angle T, we can use the triangle formula to find t.

{180}^{o} = r + s + t

By substituting r and s, we will get

{180}^{o}  =  {85}^{o}  +  {52}^{o}  + t

Hence, we can find T, which is

t =  {180}^{o}  -  {85}^{o}  -  {52}^{o}  =  {43}^{o}

Please help me I beg you substituteion with negative number & order of operations unite 2
Leto [7]

Answer:

see explanation

Step-by-step explanation:

(10)

To evaluate f(- 4) substitute x = - 4 into f(x)

f(x) = 7x - 4x + 3 = 3x + 3

f(- 4) = 3(- 4) + 3 = - 12 + 3 = - 9

(11)

To evaluate f(- 2) substitute x = - 2 into f(x)

f(- 2) = 2(- 2)² - 8 = 2(4) - 8 = 8 - 8 = 0

(12)

To evaluate g(- 3) substitute x = - 3 into g(x)

g(- 3) = - 2(- 3)² + 3(- 3) = - 2(9) - 9 = - 18 - 9 = - 27
