Answer:
A = 1 , 1 , 
Step-by-step explanation:
Given equation as
(2a -5) (a² -2a +1) = 0
Or, (2a - 5) (a - 1 )² = 0
Or, (2a - 5) (a - 1) (a - 1) = 0
So, value of a are :
2a - 5 =0, a - 1 =0, a- 1 = 0
i.e a =
and a = 1 , 1
Answer
Answer:
x= -30
Step-by-step explanation:
√3×sinx+cosx=0
√3sinx=-cosx
√3sinx/-cosx=1
-sinx/cosx=1/√3
-tanx=1/√3
(tan(180-30))=1/√3
tan(-30)=1/√3
Therefore, x= -30
Answer:
C
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
Given
See attachment
Required
Find x
The figure in the attachment is a quadrilateral and the angles in a quadrilateral add up to 360.
So, we have:
90 + 6x + 5+ 10x - 40 + 4x + 5 = 360
Collect like terms
6x + 10x + 4x = 360 - 90 - 5 + 40 - 5
20x = 300
Divide both sides by 20
x = 15
Hence, the value of x is 15
Answer:
Area = 31.5 units^2
Step-by-step explanation:
7 x 3 = 21
Area of triangle is (height x base) / 2
(3 x 7) / 2 = 10.5
21 + 10.5 = 31.5
