Step-by-step explanation:
Convert everything into decimals and add it up
Answer : B, D
Step - by - step explanation :
6/16 Divided by 2/2 --> 3/8 ( so it's not 2/8 )
6/16 Multiplied by 2/2 --> 12/32 ( so it's not 12/18 )
30/80 --> 3.75 6/16 --> 3.75
Answer:
3.since two base side are equal
4.sum of interior angle of the triangle is 180
9.base angle of isosceles triangle
16.the inscribed angle from the diameter is 90°
21.being CAE=90°
Answer:
the answer is C
Step-by-step explanation:
You have to build an equation to find the answer,
angles in a straight line add upto 180°
so your equation would be,
12x+30°=180°
-30 -30
=12x=150°
÷12 ÷12
=x=12.5°
now find the measures of the angles by using 12.5 as x.
angle EAF= 2x
=2×12.5
=25° degrees
angle DAE= 4x
=4×12.5
=50°degrees
angle CAD=6x
=6×12.5
=75°degrees
check,
30+25+50+75=180°degrees
hope this helps.......
