Answer:

all the angles of the pentagon do not add up to 540

Step-by-step explanation:

total degree in a shape

180 × (n-2)          where n is the number of side

a pentagon has 5 sides so

180 × (5-2)

= 540

100+105+72+126+127= 530

A store is having a 1/3-off sale. You want to buy a jacket that originally cost $60. What is the sale price of the jacket?
masha68 [24]
Do a proportion
1/3= x/60
Cross multiply and divide
1 x 60= 60 and 60 divided by 3 is 20
So you get $20 off
60-20= 40
Answer is $40

Law of cosines: a2 = b2 + c2 – 2bccos(A) Find the measure of Q, the smallest angle in a triangle whose sides have lengths 4, 5,
Ierofanga [76]
We are tasked to solve for the smallest angle using the law of cosines given that the three sides of the triangle are 4,5 and 6.
a=4 , b=5, c=6
Angle 1:
cosA = 5² + 6² - 4² / 2*5*6
A=41.41°

Angle 2:
cos B = 4²+6² -5² /2*4*6
B= 55.77°

Angle C:
C = 180° - 41.41° - 55.77°
C = 82.82°

The smallest angle is A which is equal to 41.41°.
