Answer:

sum of angles in a triangle is 180

so 55+80+x=180

135+x=189

x=180-135

x=45

All 3 angles of a triangle add up too 180, so 80+55= 135, 180-135 is 45, so the value of x is 45

Hello!

$\large\boxed{x^{4}}$

Recall that:

$\sqrt[z]{x^{y} }$ is equal to $x^{\frac{y}{z} }$ . Therefore:

$\sqrt[3]{x^{2} } = x^{\frac{2}{3} }$

There is also an exponent of '6' outside. According to exponential properties, when an exponent is within an exponent, you multiply them together. Therefore:

$(x^{\frac{2}{3} })^{6} = x^{\frac{2}{3}* 6 } = x^{\frac{12}{3} } = x^{4}$

When a sum of rupees hundred is divided in the ratio of 2 is to 3 find the share of each part

yKpoI14uk [10]

2x + 3x = 100

5x=100

x=100/5

x= 20

Therefore, 2x=2×20=40

3x=3×20=60

Please mark me as brinliest.......

Steph makes 90 % 90%90, percent of the free throws she attempts. She is going to shoot 3 33 free throws. Assume that the results

zmey [24]

Using the binomial distribution, it is found that there is a 0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.

For each free throw, there are only two possible outcomes, either he makes it, or he misses it. The results of free throws are independent from each other, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
