What temperature is 15 degrees lower than seven degrees Celsius and how would you work it out
Answers
The question is asking us to find the temperature which is 15 degrees lower than seven degrees Celsius.
The mathematical symbol used for lower than is a subtraction sign that is -.
15 lower than 7 degree = 7-15 = -8.
7 and 15 have opposite sign so will be subtracted .The answer will take the sign of the bigger number.
The temperature that is 15 degrees lower than seven degrees Celsius is -8°C
Hope that helps:)

Answers
Answer:
tan∠Y = 2,14
Step-by-step explanation:
First , we need to determine XY
in order to do that we use the Pythagorean theorem :
XY = √(85^2-77^2) = 36
tan∠Y = 77/36 = 77÷36 = 2,138888888889
Answer:
Step-by-step explanation:
Triangle WXY is a right angle triangle.
From the given right angle triangle
WY represents the hypotenuse of the right angle triangle.
With ∠Y as the reference angle,
XY represents the adjacent side of the right angle triangle.
WX represents the opposite side of the right angle triangle.
To determine XY, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
85² = 77² + XY²
XY² = 85² - 77² = 7225 - 5929
XY = √1296 = 36
To determine tan Y, we would apply trigonometric ratio
Tan θ = opposite side/adjacent side. Therefore,
Tan Y = 77/36
Tan Y = 2.14
