For triangle XYZ, m∠X = (7g + 12)° and the exterior angle to ∠X measures (2g + 60)°. Find the measure of ∠X and its exterior angle.

Interior angle = 49°; exterior angle = 131°
Interior angle = 131°; exterior angle = 49°
Interior angle = 96°; exterior angle = 84°
Interior angle = 84°; exterior angle = 96°

Answers

Step-by-step explanation:

the sum of the interior and the exterior angle must be 180°.

7g + 12 + 2g + 60 = 180

9g + 72 = 180

9g = 108

g = 12

interior angle = 7×12 + 12 = 96°

exterior angle = 2×12 + 60 = 84°

Answers

replace the unknown number with x and write the equation -4(x-15)=-60

-4(x-15)=-60

-4x + 60 = -60 distributive property

-4x + 60-60 = -60-60 subtract 60 from both
sides of the equal sign

-4x/-4 = -120/-4 divide -4 from both
sides

x = 30. the answer is 30
30 because u replace the unknown number with x and write the equation -4(x-15)=-60
-4(x-15)=-60
-4x + 60 = -60 distributive property
-4x + 60-60 = -60-60 subtract 60 from
both
sides of the equal sign
-4x/-4 =-120/-4 divide -4 from both sides

Can someone pls help

Answers

Answer:

b = 6

Step-by-step explanation:

steps are in the picture above

Answer:

b = 7

Step-by-step explanation:

using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , then

[tex](-14)^{8}[/tex] × [tex](-14)^{b}[/tex] = [tex](-14)^{15}[/tex]

[tex](-14)^{(8+b)}[/tex] = [tex](-14)^{15}[/tex]

since the bases on both sides are equal, both - 14, then equate exponents

8 + b = 15 ( subtract 8 from both sides )

b = 7

BCD is a straight line.
Triangle ABC is equilateral.
CE=DE
Work out the size of angle x.

Answers

The size of angle x is 44°.

Each equilateral triangle angle is measured at 60°.

∠ACB = 60°.

If two triangle sides are congruent, then the angles opposite those sides are also congruent.

∠CDE = ∠DCE

According to Angle Sum Theorem: ∠CDE + ∠CED + ∠DCE = 180°.

Substitute ∠CDE = ∠DCE into ∠CDE + ∠CED + ∠DCE = 180°

∠DCE + 28° + ∠DCE = 180°

∠DCE = 76°

The Angle Addition Postulate and the notion of a straight angle:

∠ACB + ∠ACE + ∠DCE = 180°

Substitute ∠ACE = x, ∠ACB = 60, ∠DCE = 76 into ∠ACB + ∠ACE + ∠DCE = 180°

60° + x + 76° = 180°

x = 44°
