We know that, Two angles are said to be complementary, if the sum of their measures is 90°.
<u>According to the Question</u>,
⇒ ∠ABD + ∠DBC = 90°
⇒ (2x + 30)° + (3x + 20)° = 90°
⇒ 2x + 30° + 3x + 20° = 90°
⇒ 5x + 50° = 90°
⇒ 5x = 90° - 50°
⇒ 5x = 40°
⇒ x = 40°/5
⇒ x = 8
<u>So</u>, <u>t</u><u>he measure of each angle will be</u>,
⇒ ∠ABD = (2x + 30)°
= 2 × 8 + 30°
= 16 + 30°
= 46°
⇒ ∠DBC = (3x + 20)°
= 3 × 8 + 30°
= 24 + 30°

Answer:
its A and C , Obtuse and Isosceles triangle.
Step-by-step explanation:
It's A because it's obtuse ( triangle which have measurement between 90 and 180)
Not B because Scalene triangle have three different side but the two sides are same show by the equilateral symbol.
It's C because Isosceles triangle have two sides of equal length that we can see with the equilateral symbol.
Not D because Equilateral triangle have three sides of same length but on this triangle only two sides are same.
Not E because right angle have measurement of 90 degree.
Not F because Acute triangle have measurement less than 90 degree.

Answer:
6x + 33y
Step-by-step explanation:
3(2x+11y) Distribute the 3 to the 2x and the 11y separately
6x + 33y This is the expression in expanded form.

Answer:
x • (2xt + 7y)
Step-by-step explanation:
Changes made to your input should not affect the solution: (1): "x2" was replaced by "x^2". 1 more similar replacement(s).
((5xy-((x2)•t))+2xy)+(3x2•t)
3.1 Pull out like factors : 2x2t + 7xy = x • (2xt + 7y)
x • (2xt + 7y).
