Answer:

X and Y = 66.5°.

Step-by-step explanation:

I am assuming that X and Y are the base angles, which are equal in an isosceles triangle.

X = Y = (180 - 47) / 2

= 66.5°.

Answer:

x ≈ 3.4 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin57° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{4}$ ( multiply both sides by 4 )

4 × sin57° = x , thus

x ≈ 3.4 cm ( to 1 dec. place )

Alyssa is factoring the following expression p∆2-8p-9. She said the answer is (p-1) (p +9). Is she correct? If not, explain her

Lesechka [4]

Answer:

Step-by-step explanation:

p^2-8p-9

factor out the trinomial

(p-9)(p+1)

Therefore, she's incorrect. Because (p-1)(p+9)=p^2-p+9p-9=p^2+8p-9 and that's different from p^2-8p-9.

17.775 is the most precise since it has the most decimals. However, it may not be correct.
