Answer:
Given - Two angles measures 2x and 3x
To find - size of 3x
Solution -
2x + 3x = 360° ( Make reflex angle )
5x = 360°
x = 360/5
x = 72°
3x = 3 * 72 = 216°
Is there a piece of paper that comes with the questions? Or do I just pick one? If there is a piece of paper attached, please add it to your question. Thank you!
Answer:
True
Step-by-step explanation:
The communative property states that the order in addition and multiplication dosen't matter.
Answer:
Step-by-step explanation:
4x + 3y = -1 --------------(i)
3x - 9y = 33 -------------(ii)
multiply equation (i) by 3
(i)* 3 12x + 9y = -3
(ii) <u> 3x - 9y = 33</u>
add, 15x = 30
x = 30/15
x = 2
Put x =2 in Equation (i)
4*2 + 3y = -1
8 +3y = -1
3y = -1-8
3y = -9
y = -9/3
y= -3
Answer:
A = 176.63 cm²
Step-by-step explanation:
Area of circle = π r ²
A = (3.14)(7.5)²
A = (3.14)(56.25)
A = 176.63 cm²
