Step-by-step explanation:
Sum of angles in a triangle = 180°.
Question 3:
We have 90° + 61° + (14x + 1)° = 180°.
=> 14x° + 152° = 180°
=> 14x° = 28°
=> x = 2.
Question 4:
We have 70° + 55° + (4x + 3)° = 180°.
=> 4x° + 128° = 180°
=> 4x° = 52°
=> x = 13.
Answer:
1 1/2
Step-by-step explanation:
1 1/2 + 3 1/2 = 5
6 1/2 - 5 =1 1/2
Answer:
4 is the diameter
Step-by-step explanation:
Given:
C = 4π
Formula for circumference:
C = 2πr
Work:
C = 2πr
4π = 2πr
r = (4π)/(2π)
r = 2
Diameter:
d = 2r
d = 2(2)
d = 4
We have the value -0.000125
Since this is negative value the cube number cannot be positive since it will not give an negative answer
hence the answer should be a negative number
this already eliminates the option A, B and D
now we have
![\sqrt[3]{-0.000125}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B-0.000125%7D%20%20)
![\sqrt[3]{(-0.05).(-0.05).(-0.05)}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%28-0.05%29.%28-0.05%29.%28-0.05%29%7D%20%20)
=-0.05 (option C)
