Triangle JKL is equilateral. All three interior angles have equal measures.

What is the measure of exterior angle 1?
30 degrees
60 degrees
120 degrees
130 degrees

Answers

Answer: 60 degrees

Explanation: the angles of a triangle sum to 180 degrees, and all the angles in an equilateral triangle are the same so every angle in an equilateral triangle must equal 60 degrees.

[tex] {\underline {\boxed {\Large {\bf \gray { {120}^{\circ} } }}}} [/tex]

Given :

• In ∆ JKL , all the three interior angles have equal measures.

To calculate:

• Measure of [tex] \angle [/tex] 1 ( Exterior angle )

Calculation:

Here, we can solve this question in two ways.

By exterior angle property of ∆.By linear pair.

______________________________

Let us calculate the measure of interior angles first.

→ Let the measure of each interior angle be x.

As all the interior angles of the triangle are equal,

[tex] \sf { \dashrightarrow {180}^{\circ} = {x}^{\circ} +{x}^{\circ}+{x}^{\circ} } [/tex]

[ By angle sum property of ∆ ]

[tex] \sf { \dashrightarrow {180}^{\circ} = {3x}^{\circ} } [/tex]

[tex] \sf { \dashrightarrow \dfrac{{180}^{\circ}}{3} = {x}^{\circ} } [/tex]

[tex] \sf\red { \dashrightarrow {60}^{\circ} = {x}^{\circ} } [/tex]

Therefore, measure of each interior angle of the triangle is 60°.

By exterior angle property of ∆ :

As we know that,

Sum of two opposite interior angles of ∆ = Exterior angle

[tex] \sf { \dashrightarrow \angle 1 = \angle K + \angle L} [/tex]

[tex] \sf { \dashrightarrow \angle 1 = {60}^{\circ} + {60}^{\circ} } [/tex]

[tex] \sf \green { \dashrightarrow \angle 1 = {120}^{\circ} } [/tex]

⇒ Hence, measure of angle 1 is 120°.

By linear pair:

→ [tex]\angle [/tex] 1 + [tex]\angle [/tex] J = 180°

→ [tex]\angle [/tex] 1 + 60° = 180°

→ [tex]\angle [/tex] 1 = 180° - 60°

→[tex]\angle [/tex] 1 = 120°

⇒ Hence, measure of angle 1 is 120°.

Shaquille, Lyle, and Amanda collect stamps. Shaquille has one-half the number of stamps that Lyle has. Amanda has two-thirds as many stamps as Lyle. Together they have 364 stamps. How many stamps does Amanda own?

Answers

amanda owns 112 stamps

Answer:

Amanda has 112 stamps

proof:

Lyle has 168 stamps

Shaq has 84 stamps

Step-by-step explanation:

S = number of stamps Shaquille has

L = number Lyle has

A = number Amanda has

S = 1/2L

A = 2/3L

S + L + A = 364

substituting for S and A

1/2L + L + 2/3L = 364

reduce

2 1/6L = 364

divide both sides by 2 1/6

L = 168

S = 1/2(168) = 84

A = 2/3(168) = 112

6.5% of $64.95 which can be also restructured as 6.5/100 times $64.95 which is $4.22175. Tax is added onto the final cost so he shall pay $64.95 plus $4.22175. (I think)
