Can someone help me for this question please? Why I got wrong answer. ASAP!!!
Snowcat [4.5K]

Answer:

a=8.06

A=29.74

B=60.26

Step-by-step explanation:

This is a right angled triangle and Pythagoras theorem is to be obeyed.

To get c, we follow the Pythagoras rule that says

Hyp² = Opp² + Adj²

c= Hypotenuse

c²= a² + b²

c² = 4² + 7²

c² = 65

c = √65 = 8.06

For angle A,

the opposing side to the angle = a = 4

The adjacent side to the angle = b = 7

Following trigonometry rule.

Tan A = opp/adj

Tan A = 4/7

A = Tan–¹(4/7)

A = 29.74°

For angle B,

Opposing side = 7

Adjacent side = 4

Tan B = 7/4

B = Tan-¹(7/4)

B = 60.26°

Anuta_ua [19.1K]

Answer:

27,36,45

Step-by-step explanation:

Pythagorean theorem

a^{2} +b^{2} =c^{2}

6^{2}+ 9^{2}\\ =117\\\neq 12^{2}

7^{2}+ 10^{2}\\ =149\\\neq 12^{2}

16^{2}+ 18^{2}\\ =580\\\neq 25^{2}

27^{2}+ 36^{2}\\ =2025\\= 45^{2}
