Adefective ruler was found to 11.5 in long. using this ruler, samuel was found to be 4 ft. tall. what is samuel's actual height?

choice b - 6 addition problems and 9 subtraction problems

(if you need) solution:

2 + 2 + 2 = 6

3 + 3 + 3 = 9

x+1+x1= x=2 okay that ok you make take recess

answer:

vertex angle is 66°

step-by-step explanation:

in an isosceles triangle the two base angles are congruent. the third angle is the vertex angle. in any triangle the sum of the three angles will be 180°.

let v = the vertex angle

let b = each of the base angles

v + b + b = 180°

v = b + 9 (the vertex angle of an isosceles triangle is 9 degrees more than a base angle)

substitute b + 9 for v, in the equation v + b + b = 180°

(b + 9) + b + b = 180° combine like terms to simplify

3b + 9 = 180° subtract 9 from both sides

3b = 171° divide both sides by 3

b = 57°

v = b + 9° => v = 57° + 9° = 66°

check: 57° + 57° + 66° = 180°

answer:

Ewan ko ba dyan sa math na yan HAHA
