Answer: The point (a,b) is (5,7) . Therefore, the equation of the line is y=7 .
Step-by-step explanation:
Answer:
69°, 69°, and 42°
Step-by-step explanation:
Isosceles triangles have three angles -- one vertex angle and two base angles.
The <u>base angles have the same measure</u> and the vertex angle has a different measure.
<u>Remember all triangles' interior angles sum to 180°.</u>
If the vertex angle is 42°, then the two base angles combined are:
180° - 42° = 138°
Since the base angles are the same, <u>each base angle is:</u>
138° ÷ 2 = 69°
Therefore the angles in the triangle measure 69°, 69°, and 42°.
The mistake here is that Carlos did not correctly use the distributive property (in fact, he didn't use it at all.)
14(49)
14(40 + 9)
Multiply <u>both</u> 40 and 9 by 14, then add them again.
14(40)+14(9)
560+126
686 is the correct answer.
