You just subtract 5-4 so it’s 1
The sum of the angles of a triangle is equal to 180 degrees.
We then have the following equation:
G + H + I = 180
Substituting values:
(2x + 5) + (6x - 10) + (x + 5) = 180
Clearing x we have:
(2x + 6x + x) + (5-10 + 5) = 180
9x + 0 = 180
9x = 180
x = 180/9
x = 20
Then, for the angle H we have:
H = (6x - 10) °
Substituting:
H = (6 (20) - 10) °
H = (120 - 10) °
H = 110 °
Answer:
the current measurement of angle H is:
H = 110 °
The correct answer is
C.276
2/3. you can divide the numerator and the denominator both by 3.
Answer:
85°
Step-by-step explanation:
The triangle pictured is an isosceles triangle because side KJ = LJ.
this means that ∠JKL = ∠JLK = x°
Also recall that all interior angles of a triangle add up to 180°
Hence,
180° = ∠JKL + ∠JLK + ∠KJL
180 = x + x + 10
180 = 2x + 10 (subtract 10 from both sides and rearrange)
2x = 180 - 10
2x = 170 (divide both sides by 2)
x = 170 / 2 = 85°
