Well, assuming m of angle ABD is 90 degrees, then you would add and then solve.
2x+14+x+7=90
3x+21=90
3x=69

A parallelogram is a figure which has its <em>opposite</em> sides to be <u>equal</u> and <u>parallel</u>. The <em>missing</em> reason in the proof is:
B. Substitution Angle Angle Postulate.
A <em>parallelogram</em> is a type of quadrilateral that has its <u>opposite</u> sides to be equal and parallel. The sum of its <em>internal</em> angles is
.
To <u>prove</u> that ∠ BAD ≅ ∠ DCB, we have:
Given parallelogram ABCD;
<BAC ≅ <ACD (alternate angle theorem)
<DAC ≅ <ACB (alternate angle theorem)
<BAC + <DAC = <BAD
Also,
<BCA + <DCA = <BCD
Therefore,
<BAD ≅ <DCB (Substitution Angle Angle Postulate)
Thus, the <u>missing</u> reason in the partial proof is:
option B. Substitution Angle Angle Postulate

A. It is a right triangle.
A^2 + B^2 = C^2
3^2 + 4^2 = C^2
9 + 16 = C^2
25 = C^2
Square Root
5 = C
Confirmed Right Triangle.
Given:
3 red dresses
2 white dresses
1 blue dresses
Probability that she will wear the blue dress at her party.
3 + 2 + 1 = 6 total number of outcomes.
There is only 1 blue dress so the number of ways it can happen is only 1.
probability of an event happening = number of ways it can happen / total number of outcomes
Probability = 1/6 or 0.166 or 16.6%
