Answer:
12
Step-by-step explanation:
The area of a triangle is calculated with the following formula:
(b: base, h: height (or legs))
We can use this formula to find the length of the other leg:
30 = multiply both sides with 2 to get rid of fraction
60 = b*h one of the leg's length is given as 5 so
60 = 5*h divide both sides by 5
12 = h is the length of the missing leg.
Answer:
2 cm
Step-by-step explanation:
The red triangle has legs measuring 1.2 cm and 1.6 cm.
You need x, the length of the hypotenuse.
Use the Pythagorean theorem.
(1.2 cm)² + (1.6 cm)² = x²
4 cm² = x²
x = 2 cm
Answer: 2 cm
Do you need to prove that it is equal?
If so:
SinA/cosA + sinB/cosB = (sinAcosB + sinBcosA)/cosAcosB
(SinAcosB + sinBcosA)/cosAcosB = (SinAcosB + sinBcosA)/cosAcosB
