The subtraction property of equality would be used first to solve the equation because you need to isolate n in order to solve the problem.
Answer:
x = 1.289
Step-by-step explanation:
11^x = 22
Take the log of both sides
xlog11 = log22
Divide both sides by log11
x = log22 / log11
Use calculator
x = 1.289
Solve for t
3t-7=5t
subtract 3t
3t-3t-7=5t-3t
0-7=2t
-7=2t
divide 2
-7/2=t
subsitute
6t=6(-7/2)=-42/2=-21
6t=-21
The measure of angle A is 88°.
Solution:
Given data:
∠A = (2x – 40)°, m∠B = 116° and ∠D = x°
A quadrilateral inscribed in a circle is called cyclic quadrilateral.
∠B and ∠D are opposite angles in a cyclic quadrilateral.
<em>In cyclic quadrilateral, opposite angles are supplementary. </em>
⇒ m∠B+ m∠D = 180°
⇒ 116° + x = 180
°
Subtract 116° from both sides of the equation, we get
⇒ x = 64
°
<u>To find the measure of angle A:
</u>
m∠A = (2x – 40)°
= 2(64°) – 40°
m∠A = 88°
Hence the measure of angle A is 88°.
