Solve using Pythagoras Theorem (please)​

Mathematics
1 answer:
aleksklad [387]3 years ago
3 0

Answer:

HA = 16.2 m

DE = 17 m

Step-by-step explanation:

From the base of the cuboid, HDA will form a right angle triangle, where;

DA = 15 m

HA = 6 m

HA is the hypotenuse

Using pythagoras theorem;

HA = √(15² + 6²)

HA = √(225 + 36)

HA = √261

HA = 16.155 m

Approximating to 1 decimal place gives;

HA = 16.2 m

Similarly, HDE will also form a right angle triangle.

Thus;

DE = √((HD)² + (HE)²)

HD = 16.2 m

HE = 5 m

Thus;

DE = √(16.2² + 5²)

DE = 16.95 m

Approximating to 1 decimal place gives

DE = 17 m

Answer:

A: x=6

Step-by-step explanation:

If x is equal to 6, then -3 multiplied by 6 would be equal to 18.

Then you take that 18 and subtract it from 36.

36-18=18

If f(x) = 5x + 40, what is f(x) when x = -5?
Maru [420]

Hello!

Answer:

\huge\boxed{f(-5) = 15}

f(x) = 5x + 40

x = -5

Substitute the value of "x" into the equation:

f(-5) = 5(-5) + 40

Simplify:

f(-5) = -25 + 40

f(-5) = 15.
