Answer:

140.3 cm²

Step-by-step explanation:

area of an equilateral triangle

=   \frac{\sqrt{3} }{4}  {a}^{2}

where a is the side of the triangle

= \frac{ \sqrt{3} }{4}  \times  {18}^{2}  \\  = 140.3 \: cm {}^{2}

Using the Law of Detachment, find the conclusion for the following: If two triangles are similar, then their corresponding angle
Savatey [412]

Answer:

∠ABC ≅ ∠XYZ

Step-by-step explanation:

Given: ΔABC is similar to ΔXYZ.

If two triangles are similar, then

1. the corresponding angles are congruent

2. the corresponding sides are proportional

From the options given,

AB ≅ XY is not applicable for similar triangles. Hence the option is wrong.

∠ABC ≅ ∠XYZ since  ΔABC ≅ ΔXYZ

Hence the answer is ∠ABC ≅ ∠XYZ

If a quarter of the salad is 6 ounces, then because you had 3/4th ounces of cucumber, you can do 6 multiplied by 3, which is 18.<span />

Guys i need help lol

Answer:

<em>x = 17°, m∠ A = 114°</em>

Step-by-step explanation:

We can tell that these pair of angles are corresponding, provided;

Line 1 ║ Line 2, AB ∩ Line 1 and Line 2 ⇒ corresponding ∠s ≅,

m∠ A = m∠ B ⇒ Substitute values of A and B,

6x + 12 = 3x + 63 ⇒ Subtract 3x on either side,

3x + 12 = 63 ⇒ Subtract 12 on either side of equation,

3x = 51 ⇒ Divide either side by 3,

<em>x = 17 </em>⇒ Substitute value of x to solve for m∠ A,

m∠ A = 6 * ( 17 ) + 12,

m∠ A = 102 + 12,

<em>m∠ A = 114</em>

<em>Solution; x = 17°, m∠ A = 114°</em>
