Answer:
Complementary angle 1st = 66.3°
Complementary angle 2nd = 23.7°
Step-by-step explanation:
Assume;
Complementary angle 1st = a
Complementary angle 2nd = a - 42.6°
Sum of complementary angles = 90°
So,
a + a - 42.6 = 90
a = 66.3
Complementary angle 1st = 66.3°
Complementary angle 2nd = 23.7°
Answer:
0.0265
Step-by-step explanation:
Answer:
15%
Step-by-step explanation:
37.5% of the 40% of students who walk have been late, so ...
0.375 · 0.40 = 0.1500 = 15%
of the students in the school both walk and have been late.
The probability that the student selected walks and has been late is 15%.
Triangle LMN was dilated by a scale factor of 2 followed by a translation 1 unit right and 3 unit up to form triangle L'M'N'
<h3>What is
transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformations are<em> reflection, translation, rotation and dilation.</em>
Rigid transformation preserves the shape and size of the figure. <em>Reflection, translation, rotation</em> are rigid transformations.

A)
a+b=180 and a=2(b-30) using this in the first equation gives you:
2(b-30)+b=180
2b-60+b=180
3b-60=180
3b=240
b=80 so a=100
Andre's score was 100 and Brandon's score was 80.
b)
100x-200>50x-75 subtract 50x from both sides
50x-200>-75 add 200 to both sides
50x>125 divide both sides by 50
x>2.5
