Equilateral triangle mean every sides and angles are equal so the measure of angles is 60 degrees given that has an altitude of 15 m so this mean that sin 60 = altitude / hypotenuse sqrt3 /2 = 15/hyp.hyp. = 15/(sqrt3 /2)hyp. = 30/sqrt3 = 30sqrt3 / 3 = 10sqrt3so in this way ve got that a side length is equal 10sqrt3 and the perimeter P = 3*10sqrt3 P = 30sqrt3 m so the 3rd choice is right,correct sure hope helped

x = -1/2

**Step-by-step explanation:**

add 2 which makes. 2 = -4x then divide -4 from x. which is x = 2/-4. which equals -1/2

Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil.

**chathamtownfc.net:**

0.36 = 36% probability that the land has oil and the test predicts it

**Step-by-step explanation:**

**Conditional Probability**

We use the conditional probability formula to solve this question. It is

In which

P(B|A) is the probability of event B happening, given that A happened.

is the probability of both A and B happening.P(A) is the probability of A happening.

This means that

**He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil.**

This means that

**What is the probability that the land has oil and the test predicts it?**

This is

. So0.36 = 36% probability that the land has oil and the test predicts it
