Answer:
25.5 degrees
Step-by-step explanation:
Let the first angle be x degrees, and second angle be y degrees.
<u>Condition # 1:</u>
x = 5y - 13 --------------------(1)
<u>Condition # 2:</u>
x + y = 140 -------------------(2)
Put Eq. (1) in (2)
5y - 13 + y = 140
5y + y - 13 = 140
6y - 13 = 140
Add 13 to both sides
6y = 140 + 13
6y = 153
Divide both sides by 6
y = 25.5 degrees
Now, put the value of y in Eq. (1)
x = 5(25.5) - 13
x = 127.5 - 13
x = 114.5 degrees
<u>So, the measure of smaller angle is:</u>
= 25.5 degrees

Answer:
Constant radius, AB = TU
Step-by-step explanation:
Construction: Copying of <QPR, so that;
<QPR = <TSU
The compass is placed in such a way that its two pointed legs are place at points A and B respectively to copy distance AB.
Now, place the compass at T and describe an arc to locate point U. Draw a straight line through S and U.
Therefore,
<QPR = <TSU
The step ensures that the angles are congruent by constant radius, AB = TU.
The area of ABC is ...
... area = (1/2)(BE)(AC) = (1/2)·3·4 = 6
The triangles ABC and ADC are congruent, so ...
... the area of ∆ADC is 6 square units.
