Answer:
hello,
Step-by-step explanation:
a)
In an isocele triangle, base's angles have the measure:
42+2a=180
2a=180-42
a=69(°)
b)
in a triangle, an external angle has for measure the sum of the angles not adjacents.
55+b=132
b=77 (°)
c)
in a quadrilater the sum of the (interior) angles is 2*180=360 degrees.
90+90+68+c=360
c=360-90-90-68
c=112 (°)
Answer:
208
Step-by-step explanation:
6×4=24
24×2=48
8×4=32
32×2=64
8×6=48
48×2=96
48+64+96=208
Answer:
Right now it would be

Since desend means down add -20 to -40

or

Then is goes up 35, which is positive

Therefore, the answer is -25
Hope this helps

Answer:
People should be knowledgeable about equations and inequalities because they are often used to solve day to day life problems.
Often times real life problems are modeled using equations and inequalities
Step-by-step explanation:
Inequalities are used often in real life, businesses use inequalities to control inventory, plan production lines, produce pricing models, and for shipping/warehousing goods and materials. Inequalities are used in engineering and production quality assurance.
An equation is the mathematical representation of those two things which are equal, one on each side of an 'equals' sign. Equations are useful to solve our daily life problem.
