Explanation:

Draw altitude AD to segment BC such that point D is on BC. This creates right triangles ADB and ADC.

Hypotenuses AB and AC are given as congruent. Leg AD in each triangle is congruent to itself by the reflexive property of congruence.

Then the triangles ADB and ADC are congruent by the HL congruence theorem.

Angles B and C are corresponding parts of congruent triangles, so are congruent by CPCTC.

I do not understand this question and it will be kind if you help a kid in need

Nimfa-mama [501]

Answer:

x = $\frac{mn(q-p)}{n-m}$

Step-by-step explanation:

collect the fractional terms on the left side of the equation and other terms on the right side

subtract $\frac{x-n}{n}$ from both sides

$\frac{x-m}{m}$ - $\frac{x-n}{n}$ + p = q

subtract p from both sides

$\frac{x-m}{m}$ - $\frac{x-n}{n}$ = q - p

We require the fractions to have a common denominator of mn

multiply the numerator/denominator of the first fraction by n and the numerator/denominator of the second fraction by m

$\frac{n(x-m)}{mn}$ - $\frac{m(x-n)}{mn}$ = q - p

distribute and simplify the numerators of the fractions

$\frac{nx-nm-mx+mn}{mn}$ = q - p

$\frac{nx-mx}{mn}$ = q - p

factor out x from each term on the numerator

$\frac{x(n-m)}{mn}$ = q - p

multiply both sides by mn

x(n - m) = mn(q - p)

divide both sides by (n - m)

x = $\frac{mn(q-p)}{n-m}$ → n ≠ m

In ABC, the measure of sides c is 3.9 cm If DEF is a dilation ABC with a scale factor of 2.5 what is the measure of side f

White raven [17]

Answer:

$F = 9.75cm$

Step-by-step explanation:

Given

In ABC;

$C = 3.9cm$

$Dilation = 2.5$

Required

Determine side F

In the given question;

DEF is a dilation of ABC

Comparing both triangles side by side,

Side F is a direct dilation of side C and this is calculated as follows

$F = Dilation * C$

$F = 2.5 * 3.9cm$

$F = 9.75cm$

Write the quadratic equation whose roots are 4 and 5, and whose leading coefficient is 4.

Umnica [9.8K]

Answer:

Answer: 4x² - 9x + 20 

Step-by-step explanation:

• General quadratic equation:

${ \rm{ {x}^{2} - (sum \: of \: roots)x + (product \: of \: roots) }}$

• sum of roots → 4 + 5 = 9

• product of roots → 4 × 5 = 20

• substitute:

${ \boxed{ \rm{4 {x}^{2} - 9x + 20 }}}$
