<h3>Hello There!!</h3>

<h3><u>Given</u>:-</h3>

Altitude (AB) = 9cm

Base (BC) = 12cm

Hypotenuse (AC) = ?

$\fbox \text{According To Pythagoras Theorem = }$

$\text{(Hypotenuse)² = (Altitude)² + (Base)²}$

Inserting The Values

$\text{(Hypotenuse)²} =( {9})^{2} + (12) {}^{2} \\ \\ \implies \text{(AC)} {}^{2} = 81 + 144 \\ \\ \implies \text{(AC}) {}^{2} = 225 \\ \\ \implies \text{AC} = \sqrt{225} \\ \\ \implies \text{AC} = 15$

$\therefore \text{Hypotenuse \: (AC)} = 15 \text{cm}$

Option B= <em>15cm</em> is the <u>correct answer</u>

Solve the equation using the quadratic formula. X^2-9x+3=0

Nesterboy [21]

Answer:

The answer is x= $\frac{9+\sqrt{69}}{2}$ , x= $\frac{9-\sqrt{69}}{2}$

Step-by-step explanation:

x^2=a

-9x=b

3=c

Plug into formula.

Equation: $\frac{9+-\sqrt{(-9)^2-4(1)(3)}}{2}$

Simplify the equation.

Equation: $\frac{9+-\sqrt{81-12}}{2}$

Subtract 81 and 12.

Equation: $\frac{9+-\sqrt{69}}{2}$

Spit into two equations

Equation 1: $\frac{9+\sqrt{69}}{2}$

Equation 2: $\frac{9-\sqrt{69}}{2}$

Hope this helps!

In the figure below, ZAPE and ZEPD are congruent.

Taya2010 [7]

Answer:

54degrees

Step-by-step explanation:

From the given diagram;

2<P + 136 + 74 + 42 = 360 (sum of angle at a point is 360degrees)

2<P +252 = 360

2<P = 360 - 252

2<P = 108

<P = 108/2

<P = 54

Hence the measure of <P is 54degrees
