Answer:
m<DAE = 35°
m<ECB = 37°
m<EBC = 71°
Explanation:
✔️Find m<DAE
∆ADE is said to be an isosceles triangle, therefore, the base angles, <DAE and <AED are of equal measures.
Thus, m<ADE is given as 110°. Therefore,
m<DAE = ½(180 - m<ADE)
Substitute
m<DAE = ½(180 - 110)
m<DAE = ½(70)
m<DAE = 35°
✔️Find m<ECB:
We are told that segment EC bisects <DCB. This implies that <DCB is divided into two equal angles, which are <ECD and <ECB.
This means that:
m<ECD = m<ECB
Since m<ECD is given as 37°, therefore:
m<ECD = m<ECB = 37°
m<ECB = 37°
✔️Find m<EBC:
m<EBC = 180 - (m<CAB + m<ACB)
m<CAB = m<DAE = 35°
m<ACB = 2(m<ECD) = 2(37) = 74°
Plug in the values
m<EBC = 180 - (35 + 74)
m<EBC = 180 - 109
m<EBC = 71°
They got oppressed and it caused a lot of uprising and it made them lack in the correct technology to live healthily
Sedimentary rocks cover "5%" of the "Earth’s outermost 10 Km" of "rock" while "75%" of "Earth’s continental area" is covered.
Option: C
<u>Explanation</u>:
These rocks covered 5% of the Earth's outermost 10 kilometers of rock (first %) while 75% of the Earth's continental area is covered (second %). These were originated from metamorphic rocks, pre-existing igneous and sedimentary rocks. Some common sedimentary rock types are Sandstone, shale, Limestone, Conglomerate, Chemical and Organic sedimentary rocks. These rocks are resulted from lithification of sediments, precipitate out from solution and consolidation of the remains of plants and animals and its example is Coal.
The places were there's heavy precipitation do have reduced salinity on the surface waters. The heavy rainfall through out the year, reduced the salinity on the surface of the water by little, as well as occasionally creating 'pools' of fresh water on the surface of the oceans or seas. So the statement is TRUE.
A surface weather map analyzes weather over a geographical area.
