Find measure of angle BED

Mathematics
1 answer:
Mila [183]3 years ago
3 0
The angles all form vertical angles.  The ones labeled are vertical to each other and the ones not labeled are vertical to each other.  Vertical angles are congruent, therefore, 2x + 50 = 7x.  Solving for x you get 50 = 5x and x = 10. That means that that set of vertical angles each have a measure of 70.  That's 140 so far.  Around the "circle" created by those angles is a total degree measure of 360.  So 360 - 140 = 220.  Divide that in half to get the measure of angle BED and its vertical angle AEC.  So your angle measure, BED is 110.

Answer:

2 1/3

Step-by-step explanation:

We have to find the greatest common factor of 182 and 78. We can try them out and get 26. Divide both sides by 26 and get 7/3. Simplify and end up with 2 1/3

Type a digit that makes this statement true.
posledela

The possible digits that will make 14, 213, 1__2 to be divisible by 4 are;

1, 3, 5, 7 and 9

<h3>Divisibility of Numbers</h3>

We are given the digit as 14, 213, 1__2.

Now, we see that the first of the last two digits is blank and for the give digit 14, 213, 1__2 to be divisible by 4 then the last two digits must be divisible by 4.

Now, since the last 2 digits must be divisible by 4, then it means any singe digit odd number we put in the blank space will yield a combined digit that is divisible by 4. Let us check them;

For 1; 14, 213, 112 ÷ 4 = 3, 553, 278

For 3; 14, 213, 132 ÷ 4 = 3, 553, 283

For 5; 14, 213, 152 ÷ 4 = 3, 553, 288

For 7; 14, 213, 172 ÷ 4 = 3, 553, 293

For 9; 14, 213, 192 ÷ 4 = 3, 553, 298

4 mm of Ink A is added to 10 mm of ink B, forming a mixture of inks. Ink A contains 10% blue pigment. Ink B contains an unknown
ElenaW [278]
We know that the mixture has 14 mm of ink. Of these, 35% are blue pigment, hence the mixture contains 4.9 mm of blue ink. Ink A contains 10%*4mm=0.4mm of blue ink. The difference, 4.5 mm of blue ink must have come from ink B. Thus ink B contains 4.5 mm of blue ink and is in total 10mm. After that, we can calculate the percentage; we divide 4.5/10=0.45 and this is the ratio of blue ink to total ink (in Ink B). If we transform it to percentages it is 45%

Yeah I need help with this
Mkey [24]

Answer:

$195 in total

Step-by-step explanation:

You would find the perimeter of the total garden first which equals 54 then times it by 1.5 and get 81 dollars for the gate. Then find the area of the triangle and get 120 then do 2 times 16 and get 32 then you add them together and get 152. Now with the 152 you divide it by 8 then multiple by 6 and finally add your 81 with 114 and get 195 dollars in total.
