Answer:
70°
Step-by-step explanation:
The total angle in a triangle is 180°. The total angle in a straight line is 180°. From the image attached, the ∠DCA must be greater than 45° because ∠BCA is greater than 90°. This means that ∠DCA is not 36° or 38° or 40° but it is 70°.
Therefore ∠DCA = 70°.
∠BCA + ∠DCA = 180° (angle on a straight line)
∠BCA = 180 - ∠DCA = 180 - 70 = 110°
∠BCA + ∠BAC + 40 = 180° (angle in a triangle)
∠BAC = 180 - 110 - 40 = 30°
Answer: 15/5 or 3
Step-by-step explanation:
2/5x =6/5
1/5x = 3/5
5/5x = 15/5 or 3
Answer:
Step-by-step explanation:
1. Supplementary
2. complementary
3. neither
4. These two are vertically opposite so neither.
5. Supplementary
6. They add to 90 so they are complementary
7. They add to 180 so they are supplementary.
8. These 2 are equal and vertically opposite. They are neither for this exercise.
9. Complementary: they add to 90.
Answer:9%
360,000 / 4000000=.09
.09x100= 9%
Hey there, Lets solve your question together
Question - <span>What is 400 in Expanded form ?
</span>
We know that expanded form is a spread out way to write a number by showing the value of each individual digit that contributes<span> to make the full number.
</span>
Lets use an example to show expanded form
Number - 4,265
= 4 x 1,000 + 2 x 100 + 6 x 10 + 5 x 1
Now lets solve for the number 400 in expanded form.
The number "4" is in the hundreds place
The number "0" is in the tenths<span> place
</span>
<span>The number "0" is in the One's place
</span>Therefore 400 in expanded form is 400+00+0.
<span> Hope this helps </span>
