Answer:
x = -48
Step-by-step explanation:
-4(7.5x - 8) = -5(6.3x + 8)
-30x + 32 = -31.5x - 40
-30x + 31.5x = -40 - 32
1.5x = -72
x = -72/(1.5)
x = -48
Answer:
Nope
Step-by-step explanation:
To now if a triangle is a right angle, use Pythagoras Theorem,
a^2 + b^2 = c^2
C usually be the longest side of the triangle, C = 17
Then also let a and b be 6 and 13 respectively.
6^2 + 13^2 =205
C^2 = 205
C = sqrt(205) = 14.32
therefore no this is not a right angle triangle

Answer:
C. (2x + 16) + (x) = 180°
Step-by-step explanation:
See attachment for the cyclic quadrilateral
One theorem of cyclic quadrilateral states that; opposite angles = 180°
In the attachment, the angle opposite B is D
Where B = x
D = 2x + 16
From the theorem stated above;
B + D = 180°
Substitute the values of B and D in the formula above
x + 2x + 16 = 180
From the list of given options, the correct answer is C
