Answer:
hypotenuse= 2
Step-by-step explanation:
the triangle is equal tow side so it is two side =5 cm
then the hypotenuse by Phitagors theory the triangle hypotenuse =
= 2
10 divided by 2 equals 5. to travel one mile it requires you to ride for 5 minutes. 5 times 5 equals 25.
25 minutes is your answer.
Answer:
a) 5.83 cm
b) 34.45°
Step-by-step explanation:
a) From Pythagoras theorem of right triangles, given right triangle ABC:
AB² + BC² = AC²
Therefore:
AC² = 5² + 3²
AC² = 25 + 9 = 34
AC = √34
AC = 5.83 cm
b) From triangle ACD, AC = 5.83 cm, AD = 4 cm and ∠A = 90°.
From Pythagoras theorem of right triangles, given right triangle ACD:
AD² + AC² = DC²
Therefore:
DC² = 5.83² + 4²
DC² = 34 + 16 = 50
DC = √50
DC = 7.07 cm
Let ∠ACD be x. Therefore using sine rule:

Its already fully simplified.
3*7-6
21-6=15
15 is the answer
