16. Solve for "x". a. 6 b. 100 c. 36

erastovalidia [21]

Answer:

A. 6

Step-by-step explanation:

Using the Pythagorean theorem which states that: Hypotenus² = Opposite² + Adjacent²

Where: hypotenus = 10, opposite = x, adjacent = 8

So:

${10}^{2} = {x}^{2} + {8}^{2}$

Solving for x

$100 = {x}^{2} + 64$

Collect like terms to make x the subject of formula

$100 - 64 = {x}^{2} →36 = {x}^{2}$

$36 = {x}^{2} ⟹ {x}^{2} = 36$

square root both sides of the equation to find the value of x

$\sqrt{ {x}^{2} } = \sqrt{36} →x = 6$

Therefore: Option A is correct

Proving trapezoid theorems Geometry

Artist 52 [7]

Answer:

ΔABD ≅ ΔACD by SAS, therefore;

$\overline {BD} \cong \overline {CA}$ by CPCTC

Step-by-step explanation:

The two column proof is presented as follows;

Statement ${}$ Reason

ABCD is a trapezoid ${}$ Given

$\overline {BA} \cong \overline {CD}$ ${}$ Given

$\overline {BC} \parallel \overline {AD}$ ${}$ Definition of a trapezoid

ABCD is an isosceles trapezoid ${}$ Left and right leg are equal

∠BAD ≅ ∠CDA ${}$ Base angle of an isosceles trapezoid are congruent

$\overline {AD} \cong \overline {AD}$ ${}$ Reflexive property

ΔABD ≅ ΔACD ${}$ By SAS rule of congruency

$\overline {BD} \cong \overline {CA}$ ${}$ CPCTC

CPCTC; Congruent Parts of Congruent Triangles are Congruent

SAS; Side Angle Side rule of congruency
