Answer:
m = 10 , n = 5
Step-by-step explanation:
using the cosine and tangent ratio in the right triangle and the exact values
cos45° = 
and tan45° = 1 , then
cos45° = 
= 
= ( cross- multiply )
m = 5 × = 5 × 2 = 10
-----------------------------------------
tan45° = 
= 
= 1 , then
n = 5
Answer:
13/4
Step-by-step explanation:
We can plug in the values of this point to find b
-4 = 17 (3) +b
We will multiply 17 times 3
-4 = 51 + b
We then subtract by 51 on both sides
-55 = b
So the full equation will be
y = 17x - 55
A) 95.8 % of £36 will be the new price
B) The answer to part A as a decimal is £34.488
C) The new price is £34.488
<h3><u>Solution:</u></h3>
Given that the price of a pedicure decreases by 4.2% from £36 on promotion
<em><u>A) What percentage of £36 will the new price be ?</u></em>
Given that £36 is decreased by 4.2 %
New price = 36 – 4.2% of 36
Now we have to find what percentage of £36 will the new price be
x % of 36 = 34.488
<em><u>B) Write your answer to part a as a decimal.</u></em>
Now, we have to find the new price in decimal form.
<em><u>C) Work out the new price.</u></em>
As we calculated, the new price is £34.488
Answer:
Complementary angles, adjacent angles
Step-by-step explanation:
Which relationships describe angles 1 and 2?
Options: Complementary angles, vertical angles, supplementary angles, adjacent angles
Angles 1 and 2 are opposite to the 90° angle. So, the angles' relationship to that angles is a vertical angle, meaning that the two add up to 90°.
Complementary angles add up to 90°, so this option is correct.
Vertical angles are the pairs of opposite angles formed by two intersecting lines. Because the two angles do not follow this definition, this option is incorrect.
Supplementary angles add up to 180°. However, we know that the two add up to 90°, so this option is incorrect.
Adjacent angles are angles that are next to each other, so this option is correct.
I hope this helps! Feel free to ask any questions!
