Find the measures of the four numbered angles

Mathematics
1 answer:

5 0
First, find out x
x+15+2x+15=180
3x+30=180
3x=150
x=50
so the two angels are x+15=65(let's name is ∠5 for convenience), and ∠6= 2x+15=115
notice the two inner lines are marked as congruent, so 
∠4=∠5=65
∠1=180-∠4-∠5=180-65-65=50
Name the right bottom angle ∠7, ∠3=∠7 and ∠3+∠7=the exterior angle 100 degree, therefore, ∠3=50
∠2+∠3=∠4, therefore, ∠2=∠4-∠3=65-50=15
∠1=50, ∠2=15, ∠3=50, ∠4=65

Find the mode and median of the data. A. mode = 41 median = 72 B. mode = 72 median = 94 C. mode = 94 median = 94 D. mode = 94 me
SashulF [63]
Mode means the number that apperss the most
median is the number in the middle when you arrange them in numerical order


ok so
you take the unbers fom the left most collumn and pair it with each number in the right side of the line, the left collumn is the tens place and the right hand side is the ones

so the th enumbers are

32,41,41,50,56,57,62,70,70,72,72,72,73,74,91,92,94,94,94,94


mode=most common number
94 appears 4 times which is most
mode=94

median is number in very middle number
20 terms
72 is in middle


mode=94
72=median

The perimeter of a rectangle is 48 cm. The length is 6cm less than twice the width. Which system would model this situation and
fenix001 [56]
The easiest way to solve this question would be to subtract the 6 from the 48 which results in 42. Then because the length is twice it’s width we divide the 42 by 3 which gives us 14. Therefore the width is 14 and the length is double of fourteen which is 28

M_6 is (2x – 5)º and m_8 is (x + 5)º.
HACTEHA [7]

m_6 + m_8 = 180º because they form a straight line.

So, (2x-5) + (x+5) = 180

    3x = 180

      x = 60

So, m_115º    (2•60 - 5 = 115)

Also, because the two lines are parallel m_6 = m_3 by alternate interior angles.

So, m_3 = 115º
