Answer:

The answer is C.

Step-by-step explanation:

So to get the answer add 90+30= 120

Then take 180-120=60 (which is your leftover angle)

Answer:

C. 60º


Step-by-step explanation:

A triangle is called a right triangle when one of it's angle measures 90°.

We have been given the second angle as 30°.

The angles in a triangle add up to 180°.

∴ leting the third angle to be X;

X + 30° + 90° = 180°

X + 120° = 180°

X = 180° - 120°

   = 60°

Angelina_Jolie [31]

Answer:

The number of fringes at d=-2 is given as 20.

Step-by-step explanation:

Question

A Galapagos cactus finch population increases by half every decade. The number of finches is modeled by the expression

,

where d is the number of decades after the population was measured. Evaluate the expression for d = −2

Given :

The number of  finches is modeled by the expression  :

⇒ 45\cdot1.5^d

where d is the number of decades after the population was measured.

To evaluate the expression for d=-2

Solution:

In order to evaluate the given expression to find the number of finches at d=-2, we will plugin -2 for d in the expression and simplify it.

Plugging in d=-2 in the expression:

⇒ 45\cdot 1.5^{-2}

Using negative exponent property. [a^{-x}=\frac{1}{a^x}

⇒ 45\cdot \frac{1}{1.5^2}

⇒ 45\cdot \frac{1}{2.25}

⇒ 20   (Answer)

Thus, the number of fringes at d=-2 is given as 20.

This means the number of fringes two decades ago was 20.
