Answer:

m∠QRS = 52°

Step-by-step explanation:

From the given figure,

In right triangles ΔRQT and ΔRST,

QT = TS = 7.5 units [Given]

RT ≅ RT [Reflexive property]

ΔRQT ≅ ΔRST [By HL theorem of congruence]

Therefore, m(∠QRT) = m(∠SRT) = 26° [CPCTC]

m(∠QRS) = 2m(∠QRT)

= 2×(26°)

= 52°

A line that includes the points (8,0) and (9,s) has a slope of 9. What is the value of s?

scZoUnD [109]

Answer:

s = 9

Step-by-step explanation:

We can find the slope given two points

m = (y2-y1)/(x2-x1)

9 = (s-0)/(9-8)

9 = (s)/1

S = 9

$\begin{gathered} P(A)=\frac{3}{5} \\ P(B)=\frac{3}{4} \\ P(A\cap B)=\frac{3}{7} \\ P(A|B)=\text{?} \\ P(A|B)=\frac{P(A\cap B)}{P(B)}=\frac{\frac{3}{7}}{\frac{3}{4}}=\frac{3\cdot4}{3\cdot7}=\frac{4}{7} \\ P(A|B)=\frac{4}{7} \\ The\text{ probability that A occurs given B is }\frac{4}{7} \end{gathered}$
