How do I solve this geometry proof?
viktelen [127]

I don't remember the names of the theorems at all, but we know that AD ≈ DE ≈ EB (Segment Addition). Which means <ACD ≈ <DCE ≈ <ECB (not completely sure how to prove this). Therefore, <1 ≈ <2. (Don't forget to state that <1 ≈ <ACD and <2 ≈ <ECB). With this and Angle Addition, we know that <ACE ≈ <DCB, so with SAS Congruence Theorem, we can prove ΔACE ≈ ΔBCD.

Hope that helps

Decide whether ABC is a right angle triangle
muminat
The triangle is not a right angle

AC = 22 - 8 - 5 = 9
AC² = AB² + BC²
81 = 64 + 25
81 isn't equal to 89, the triangle is not a right angle

Harry ,Louis and Niall Are working with exponents. Harry claims 4^2•4^5=4^10 Louis claims 4^2•4^5=4^7 Niall claims 4^2•4^5=16^7
slavikrds [6]

Answer:

Louis is correct

Step-by-step explanation:

we know that

When multiplying two powers that have the same base, you can add the exponents

so

a^{n} a^{m}=a^{n+m}

so

In this problem we have

4^{2} 4^{5}=4^{2+5}=4^{7}

therefore

Louis is correct

ioda

Answer: x=\frac{35±\sqrt[]{6505} }{22}

Step-by-step explanation:  x=5.25698091…,−2.07516273…

The <u>roots</u> (zeros) are the x values where the <u>graph</u> <u>intersects</u> the <u>x-axis</u>. To find the <u>roots</u> (zeros), replace y with 0 and solve for x.
