Answer:
∠ R ≈ 39°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos R = = = , then
∠ R = ( ) ≈ 39° ( to the nearest degree )
Answer:
x = 15
LM = 18
MN = 18
LN = 18
Step-by-step explanation:
To find x:
x + 3 + 2x - 12 + 33 - x = 54
2x + 24 = 54
2x = 54 - 24
2x = 30
x = 15
LM:
x + 3
15 + 3
18
MN:
33 - x
33 - 15
18
LN:
2x - 12
2(15) - 12
30 - 12
18

Step-by-step explanation:
Answer:
ASA
Step-by-step explanation:
You are given 2 equal sets of angles.
<ABD and <ACD (right angles)
<BAD and <CDA (bisected angle)
You can get <ADB = <ADC because every triangle has 180 degrees. You know two of the angles: you can show that the 3 rd set are equal a subtraction postulate.
AD = AD (Reflexive property)
The triangles are congruent by ASA
If AAS is acceptable then it is correct in this case.
AD = AD
The two right angles are equal
The two angles created by the angle bisector are equal.
These three facts give AAS, but please see my comment below.
Bananas =17.50 , cabbage =12.50 =5 pounds more of bananas.
