Answer:

Well a triangle itself is worth 180 degrees (Inteirior angles)

your given “a” “b” and you need to find c.

So you can subtract

A is 50

B is 55

<BCA= 180- 55-50

Is the answer (b)

Answer:

Step-by-step explanation:

A triangle's angles all add up to 180 degrees. If m∠A is 50 and m∠B is 55 then m∠C is 75.

m∠C = 180 - (m∠A - m∠B); which is 180 - 105

180 - 105 is 75; Therefore, m∠C is 75 degrees

Proof: 50 + 55 + 75 = 180

Answer:

n = 8

Step-by-step explanation:

Follow the question when turning the word equation into an equation

Because we know this is a quadratic equation, the product is a result of n multiplied by itself

$n^{2} -4=60$

Solve for n

$n^{2} =64$

$\sqrt{n^{2} } =\sqrt{64}$

n = 8

HELLPPPP ME !!!1 i dont need a explanation

Answer:

Part 1: 30.42

Part 2: 33.598 (33.6)

Step-by-step explanation:

Part 1:

First you're going to start by subtracting 142 from 360 to get 218

Then you're going to divide 218 by 360 to get a rounded .61

Then you're going to multiply that by pi (3.14)

.61 x 3.14 = 1.9

Then you're going to square 4

4 x 4 = 16

Then multiply 1.9 x 16

Your answer should be 30.42

Part 2:

Since it gives you the measurment you need, you're going to skip the subtracting and just divide 107 by 360

This gives you .3 (rounded)

Multiply by pi

.3 x 3.14 = .94

multiply by square of 6 (36)

.94 x 36 = 33.84

if you shove it all into a calculator without rounding inbetween at all you get 33.59

If the probability of rain is 0.75, the probability of fog is 0.25, and the probability of rain and fog is 0.25, what is the

alexgriva [62]

Answer:

$P(A \cup B) = 0.75$

Step-by-step explanation:

There are two scenarios:

A - Rain

B - Fog.

The probability of rain or fog is determined by the Addition Rule, given that A and B are not mutually excluyent:

$P(A\cup B) = P(A) + P(B) - P(A\cap B)$

$P (A\cup B) = 0.75 + 0.25 - 0.25$

$P(A \cup B) = 0.75$

3x^2-5x-7 find the sum and product

Bad White [126]

Answer:

$s = \frac{5}{3}$

$p = \frac{7}{3}$

Step-by-step explanation:

for this equation

a=3

b= -5

c = -7

The sum of equal to

$- \frac{b}{a}$

and the product is equal to

$\frac{c}{a}$

. All you do is replace the values. You can prove both of those using the quadratic formula.
