Answer: ask your teacher/Guardian
Step-by-step explanation: It is it a division question?
Answer:



Step-by-step explanation:
From the diagram, quadrilateral BCEF is a cyclic quadrilateral.
Opposite angles if a cyclic quadrilateral sum up to 180°

The diagonals intersect at D to form two pairs of vertical angles, and vertical angles are congruent.

Also sum of angles in triangle CBD is 180°.

5 rational numbers between 0.5 and 0.6 can be any 5 numbers up to any number of decimal places that lies between 0.5 and 0.6. Or, it can also be 0.5124, 0.5676, 0.588, 0.59, 0.5789.S
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for B
B = 180° - (90 + 40)° = 180° - 130° = 150°
--------------------------------------------------------------
sin40° =
= 
Multiply both sides by 21
21 × sin40° = a, thus
a ≈ 13.5 ( to the nearest tenth )
--------------------------------------------------------------
cos40° =
= 
Multiply both sides by 21
21 × cos40° = b, thus
b ≈ 16.1 ( to the nearest tenth )
Answer:
b=8d+9c+3
Step-by-step explanation:
Multiply:
1x3=3
Rewrite Equation:
b=8d+9c+3
Hence, the correct answer is b=8d+9c+3
