Given: AB ≅ BC , AE ≅ FC Prove: m∠AEC=m∠AFC
Answers
Answer:
EC/AB = FC/MA
Step-by-step explanation:
We are given AB
≅
BC that means that side AB and side BC are equal also we know that angle opposite to equalt
sides are equal.
Hence, ∠BAE=∠BCE-------(1)
Also ∠AEB=∠CEB.
Now we are given that: ∠ABC = 130°30’ i.e. in degrees it could be given as:
60'=1°
30'=(1/2)°=0.5°
Hence ∠ABC = 130°30’=130+0.5=130.5°
Also we know that sum of all the angles in a triangle is equal to 180°.
Hence,
∠BAE+∠BCE+∠ABC=180°.
2∠BAE+130.5=180 (using equation (1))
2∠BAE=49.5
∠BAE=24.75° (DIVIDE BOTH SIDE BY 2)
Now in triangle ΔBEC we have:
∠BEC=90° , ∠BCE=24.75°
SO,
∠BEC+∠BCE+∠EBC=180°.
Hence, 90+24.75+∠EBC=180
∠EBC=180-(90+24.75)
∠EBC=65.25°
Now we are given AE = 10 in
Also ∠BEA= 90°.
And ∠BAE=24.75°; hence using trignometric identity to find the measure of side BE.
\begin{gathered}\tan 24.75=\dfrac{BE}{AE}=\dfrac{BE}{10}\\\\BE=10\tan 24.75-------(2)\end{gathered}tan24.75=AEBE=10BEBE=10tan24.75−−−−−−−(2)
similarly in right angled triangle ΔBEC we have:
\begin{gathered}\tan 24.75=\dfrac{BE}{EC}\\\\\tan 24.75=\dfrac{BE}{EC}\\\\EC=\dfrac{BE}{\tan 24.75}------(3)\end{gathered}tan24.75=ECBEtan24.75=ECBEEC=tan24.75BE−−−−−−(3)
Hence, using equation (2) in equation (3) we get:
EC=10 \text{in.}EC=10in.
Hence AC=AE+EC=10+10=20 in.
Hence side AC=20 in.

First of all you would take 102 and subtract 24 which equals 78 . Then you would divide 78 by 2 and your answer will be 39 . To check your answer you will take 24 39 , 39 and add it all together . if it comes out to 102 you have the correct answer . So you are using subtraction division and addition
Angle 1 is in a triangle with angle 4 and a 53 degrees angle. What is the sum of the measures of those two angles?
Answers
Angle 3=23 because 180-30-127=53
Angle 1=37 because 90-53=37
Angle 4=90
Angle 1+4=127
The value of angles are in given triangle as:
Angle 1 = 37°, angle 2 = 127°, angle 3 = 23°, and angle 4 = 90°.
Given that the triangle attached below.
Also given angle one with angle four and a 53° angle.
Since the sum all three angle of triangle is equal to 180°.
In triangle ABC,
∠A + ∠B + ∠C = 180
Angle 1 + 90 + 53 = 180
Angle 1 = 37°
Also the angle 4 is equal to 90°.
The angle 2 is equal to 127°, because 180 - 53 = 127°
Now, in triangle ACD,
∠C=127° and ∠D = 30
∠A + ∠C + ∠D = 180
Angle 3 + 127 + 30 = 23
Hence, the value of angles are:
Angle 1 = 37°
Angle 2 = 127°
Angle 3 = 23°
And angle 4 = 90°

suppose you are measuring peanut butter. begin with 1 1/2 c cold water in a container. after you add the peanut butter to the water, the water level reads 2 1/4 c.what is the volume of the peanut butter. explain.
Answers
Volume of the peanut butter is 3/4 c.
What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Here is given the method to measure the peanut butter.
Volume of the cold water at the beginning = 1 1/2 c
= 3/2 c
Volume of the water after adding the peanut butter = 2 1/4 c
= 9/4 c
Volume of peanut butter = 9/4 c - 3/2 c
= (9/4) - (6/4)
= 3/4 c
Hence the volume of the peanut butter is 3/4 c.
