Solve for x please will mark brainliest
cestrela7 [59]

Answer:

x = 6

Step-by-step explanation:

This shows that the angle being split is 90 degrees.

<em>We know that 32 degrees are already known so we can do </em><em>90 - 32 = 58</em>

Now we know that 58 is the angle of 9x + 4

9x + 4 = 58

Subtract 4 from both sides

9x = 54

Divide both sides by 9 to isolate x

x = 6

AlexFokin [52]

Step-by-step explanation:

the total angles in the triangle are 180°

so,

63° + 57° + ∠2 = 180°

120° + ∠2 = 180°

∠2 = 180° - 120°

∠2 = 60°

One angle of an isosceles triangle measures 110°. Which other angles could be in that isosceles triangle? Choose all that apply.
andre [41]

Answer:

Therefore the correct option is 2. 35 degree.

\angle ABC=\angle ACB=35\°

Step-by-step explanation:

Consider an Isosceles Triangle, Δ ABC where,

∠BAC = 110°

TO Find:

∠ ABC = ∠ACB = ?

Solution:

For an Isosceles Triangle

Base Angles are equal

∴\angle ABC=\angle ACB=x\ (say)

Now,

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

\angle A+\angle B+\angle C=180\\\\110+x+x=180\\\therefore 2x=180-110=70\\\therefore x=\dfrac{70}{2}=35\°

Therefore,

\angle ABC=\angle ACB=35\°
