Mathematics

Ratling [72]3 years ago

Answer: X would equal -8

Step-by-step explanation: Starting off, you would cross multiply, so 414 times 1 = (x-10) times -23. It's similar to the one I answered before, just with different numbers. 414 = -23 (x-10). After that, distribute to get: 414 = -23x +230. Then subtract 230 from both sides and divide by -23 to get x. Hope that helps.

Furkat [3]
1. how many times 47 fits on 985? 20×47=940
try higher: 47×21=987. So use 20. subtract 985-940=45. how many times does 47 fit on 45? 0 so the answer should be 20 remainder 45

HELPPPPP Find the missing parts of the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropria
Romashka-Z-Leto [24]

The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that a = 8.6 in, b = 13.9 in. and c = 16.5 in. Using cosine rule:

c² = a² + b² - 2abcosC

16.5² = 8.6² + 13.9² - 2(8.6)(13.9) * cosC

C = 91.2°

Also:

a² = b² + c² - 2bccosA

8.6² = 16.5² + 13.9² - 2(16.5)(13.9) * cosA

A = 31.4°

A + B + C = 180° (angles in a triangle)

31.4 + B + 91.2 = 180

B = 57.4°

The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°
