1) Either \ell \parallel p or \ell ∦ p (only two possibilities)

2) Assume \ell \parallel p (one of two possibilities)

3) \angle 1 \cong \angle 2 (if two parallel lines are cut by a transversal, the corresponding angles are congruent)

4) But \angle 1 is not congruent to \angle 2 (given)

5) So \ell ∦ p (only other possibility)

Can someone help me on this math problem.
nekit [7.7K]

In the rhombus, the diagonals are perpendicular.

We know, the sum of the measures of the triangle is equal 180°.

Therefore we have the equation:

(2x-15)+3x+90=180

2x-15+3x+90=180        <em>combine like terms</em>

(2x+3x)+(-15+90)=180

5x+75=180        <em>subtract 75 from both sides</em>

5x=105              <em>divide both sides by 5</em>

\boxed{x=21}

<h3>Answer: x = 21°</h3>

Joe was planning a business trip to Canada, so he went
nika2105 [10]

Answer:

2203.20 pesos

Step-by-step explanation:

Joe's original amount was $200

#We convert this amount to $CDN:

\$1=1.02\$CDN\\\\=200\times 1.02\\\\=204\$CDN

Joe now has to convert the Canadian dollars to Mexican pesos(at a rate of 10.8 pesos per $1 CDN):

=204\times10.8\\\\=2203.2

Hence, he gets a total of 2203.20 pesos in exchange for his Canadian dollars.
