<h3>▄▄▄▄▄▄▄▄▄▄▄▄▄▄</h3>

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°

<h3> = 54° ▄▄▄▄▄▄▄▄▄▄▄▄▄▄</h3>

Lunna [17]

\huge\boxed{99}

First, find out how much 10% of 90 is.

90*10%\ =\ 90*0.1\ =\ 9

Now, just add that to 90.

90+9=\boxed{99}

There are 99 members now.

What is the vector sum of (7,5) and (13,-5)
kolezko [41]

The vector sum of  two vectors as (7,5) and (13,-5) is given by v_1+v_2=20i+0j which can be written in point form as  (20,0) .

<u>Step-by-step explanation:</u>

Here we have , two vectors as (7,5) and (13,-5) Which are represented as :

v_1=7i+5j\\v_2=13i-5j

Addition of vector is as same as normal addition of integers as :

⇒ v_1+v_2=7i+5j+(13i-5j)

⇒ v_1+v_2=(7+13)i+(5-5)j

⇒ v_1+v_2=20i+0j ,

where i & j are the unit vectors in direction x-axis and y-axis respectively.

The vector sum of  two vectors as (7,5) and (13,-5) is given by v_1+v_2=20i+0j which can be written in point form as  (20,0) .
