Answer: 91
Step-by-step explanation: 6.5 x 14 = 91
Step-by-step explanation:
To find the gradient:
y2-y1/x2-x1
Pick any two coordinates
11)
(4,3) and (1,-1)
-1-3= -4
1-4= -3
-4/-3 = 1.3(1dp)
12)
(0,1) and ( 2,-2)
-2-1= -3
2-0= 2
-3/2= -1.5
Might be wrong but this is what I got from what I have learnt.
Hope this helps! :)

Step-by-step explanation:
(a)
The shaded figure is a trapezium with area (A)
A = 0.5 h(a + b)
where h is the perpendicular height and a, b the parallel sides, thus
A = 0.5 × 10 × (8 + 14) = 5 × 22 = 110 cm²
(b)
The volume (V) of the prism is calculated as
V = area of end face × depth
= 110 × 3 = 330 cm³

r = 14 i think
Step-by-step explanation:
take the lowest degree angle and subtract it from the higher one and BOOM u got ur answer :) please mark me brainliest I need it to rank up
Answer:
x= 56 degree
Step-by-step explanation:
sin x= opposite/ hypotenuse
sin x= 66/79
sin x=0.84
sin-1(0.84)= x
x= 56 degree
