Answer:
*The measure of angle <CBA is equal to the measure of angle <DBE.
*The measure of angle CBD is equal to the measure of angle ABE.
*The sum of the measures of angles CBD and CBA is 180 degrees.
Step-by-step explanation:
Since lines CE and AD bisects at D, they form two pairs of vertical angles that are congruent to each other. The vertical angle pairs formed are:
<CBD and <ABE;
<CBA and <DBE
Thus:
m<CBD = m<ABE;
m<CBA = <DBE = 37°
Also, m<CBA + m<CBD = 180° (supplementary linear pair)
m<ABE + m<DBE = 180° (supplementary linear pair)
Therefore, the following statements are TRUE:
*The measure of angle <CBA is equal to the measure of angle <DBE.
*The measure of angle CBD is equal to the measure of angle ABE.
*The sum of the measures of angles CBD and CBA is 180 degrees.
Answer:
1.668 S
Step-by-step explanation:
We are given that
Product
For first order reaction,
Rate constant=k=
Temperature=
We have to find the time taken by the reaction when concentration of A to decrease from 0.790 M to 0.230 M.
Substitute the values then we get
Hence, it would take 1.668 s for the concentration of A to decrease from 0.790 M to 0.230 M.
Answer:
3x = - 6
Step-by-step explanation:
Three times a number is at most negative six
3 times a number would be 3 times x, is means the equal sign (=)
3x = - 6
Answer:
negative
Step-by-step explanation:
negative plus negative is negative
