(b) is the answer.
Step-by-step explanation:
By the Pythagorean Theorem,
A² + B² = C²
Where:
A = Length of side 1
B = Length of side 2
C = Hypotenuse
This rule applies to all right-angled triangles.
The length of the hypotenuse of a right-angled triangle is always the largest value.
Therefore, we can test the answers with the equation above.
(a)
8² + 18² = 20²
64 + 324 = 400
388 ≠ 400
The rule of Pythagorean theorem doesn't work on a, so (a) is not a right-angled triangle.
(b)
12² + 35² = 37²
144 + 1225 = 1369
1369 = 1369
The rule of Pythagorean theorem works here, so (b) is a right-angled triangle.
Answer:
C, linear
Step-by-step explanation:
C is the only one with the (1,8) corriant
And it is linear because it has a pattern
Answer:
(- ∞ , 88)
Step-by-step explanation:
1) m - 88 < - 176
add 88 to both sides
2) m < -88
3) interval notation: ( - ∞, 88)
In the given figure,
Angle 108° + 12x = 180°
because they for pair of co- interior angles which are supplementary.
so,
hence , value of x = 6°
Answer:
Step-by-step explanation:
remaining cups = total cups - used caps
let remaining cups be = x
total cups = y = 8
used cups = z= 
Hence x = y-z
x = 8 -
= 
- 
= 
= 
=
x=
Remaining cups =
