A triangle has sides with lengths of 18 centimeters, 68 centimeters and 74 centimeters. Is it a right triangle?

18^2 + 68^2 =

= 324 + 4,624

= 4,948

74^2 = 5,476

4,848 is not equal to 5,476.

Since the sum of the squares of the lengths of the two shorter sides is not equal to the square of the length of the longest side, the triangle is not a right triangle.

Alex_Xolod [135]

Answer:

471.2 cm³ missing

Step-by-step explanation:

jars are cylinders

volume of cylinder = π * r² * h

h=10

r=5

v=785.4 cm³ of a full jar

r stays the same = 5

h = 4

v= 314.2 cm³ left in the jar

whats missing is the full-left

785.4-314.2=471.2 cm³ missing

Need help with this question; What is the measure of one leg of a right angle given that the hypotenuse measure 14cm and the oth
melamori03 [73]

Answer:

11.5 cm

Step-by-step explanation:

The dimensions of a right angled triangle can be determined using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

a² + 8² = 14²

a² + 64 = 196

a² = 196 - 64

a² = 132

find the square root of 132

a = 11.5 cm

3. Let sin 21 = 0.358. What is the value of x for cos x=0.358?
r-ruslan [8.4K]

Answer:

\cos(69)

Step-by-step explanation:

We will use the co-function identity for sine, where:

\sin(x)=\cos(90-x)

Since sin(21)=0.358=cos(x). This means that:

21=90-x

Solve for x. Add x to both sides:

x+21=90

Subtract 21 from both sides:

x=69\textdegree

Hence:

\sin(21)=\cos(69)\approx0.358
