Answer:
Step-by-step explanation:
we have that
------> by supplementary angles
Substitute the values and solve for x
Find the value of angle R
Find the value of angle Q
Step-by-step explanation:
c²= 8²+6²
c²= 64+36
c²=100
c=10
ACD by AAS.
We're given m1 = m2, ADC = ADB, and both triangles share AD, so it must be AAS.
ABD by SAS.
We're given AB = AE and AC = AD, but the middle part is a mystery. We're not given BD and CE/ADB and ACE so it's pretty hard to know. Could be SAS or SSS. If you have either BD and CE, it's SSS. If you have ADB and ACE, it's SAS.
Took Geometry 4 years ago so I'm a bit iffy on the second. Forgive me D:
-12x^4 + x^3 + 10x - 4
To write in standard form means to order the terms in order of highest to lowest degree.
"Degree" means exponent. So in simpler words, you order the terms in order of descending exponent value. Ex: x^4 - x^3 + x^2...
Also, you write the terms with variables before the terms that are only a constant, which is why 10x comes before -4.
