Answer:
Step-by-step explanation:
By triangle sum theorem,
Sum of all angles of a triangle is 180°.
m∠1 + m∠2 + m∠3 = 180°
(m∠1 + m∠3) + m∠2 = 180°
2(m∠1) + 70° = 180° {Given → m∠1 = m∠3]
2(m∠1) = 110°
m∠1 = 55°
Therefore, m∠1 = m∠3 = 55°
Answer:
Width: 15.8 ft
Length: 32ft
Step-by-step explanation:
The area of a rectangle is A=lw. Therefore, it can be represented here as: A=(4ab^2)(2ab).
Now, you can distribute.
4*2=8
a*a=a^2
b^2*b=b^3
The simplified expression is 8a^2b^3.
Hope this helps!!
we know that
If two angles are congruent, that means, that the angles are equal
so
the measure of an angle congruent to a 47° is 47°
